OZRIC TENTACLES
A pioneering British band formed in 1983 by guitarist Ed Wynne and a group of like-minded musicians in Somerset, England. Originally emerging from the free-form jam sessions at Stonehenge Festival, the band quickly became a staple of the UK’s underground festival circuit, captivating audiences with their mesmerizing blend of psychedelic rock, space rock, electronic music, and world influences.
​
Their mission was to bridge the cosmic soundscapes of 1970s space rock—drawing inspiration from bands like Hawkwind, Gong, and Pink Floyd—with the vibrant dance and rave culture that defined the 1990s. Ozric Tentacles’ music is characterized by swirling synthesizers, intricate guitar work, hypnotic rhythms, and a rich tapestry of global sounds, including Middle Eastern scales and reggae-inspired grooves.
​
The band’s lineup has evolved over the years, but Ed Wynne has remained the creative force behind their ever-expanding sonic universe. Notable members have included Joie Hinton (keyboards), Merv Pepler (drums), and John Egan (flute), each contributing to the band’s signature sound.
Ozric Tentacles are renowned for their electrifying live performances, which often feature extended improvisations and immersive visual effects. They have released more than 30 albums, including classics like Pungent Effulgent (1989), Erpland (1990), and Jurassic Shift (1993), as well as more recent works such as Space for the Earth (2020).
​
Their influence extends beyond the psychedelic and progressive rock scenes, inspiring generations of musicians and festival-goers with their genre-defying approach and commitment to musical exploration. Ozric Tentacles remain a psychedelic highlight at major festivals like Glastonbury, Stonehenge, and countless others, continuing to transport listeners to otherworldly realms with every performance.

THE ULTRA ELECTRIC MEGA GALACTIC
New band of psychedelic guitar wizard Ed Mundell. He is a founding member of New Jersey stoner band The Atomic Bitchwax and later joined Monster Magnet as lead guitarist. His first recorded appearance with the band was 1993's Superjudge album. In the span of 18 years he played on seven Monster Magnet albums in total between 1992 and 2010, and then left Monster Magnet to collaborate with new producers, songwriters and musicians. Mundell's style is heavily influenced by psychedelic 70s rock such as Jimi Hendrix and Tommy Bolin.
In 2010 Mundell started to form a new project, "The Ultra Electric Mega Galactic", whose self-titeld debut album released January 2013.
​Coming with their 3th album in 2026, it's the perfect time to invite them back to the EU after 12 years off absence.
ATOMIC ROOSTER
Atomic Rooster is a legendary British rock band originally formed in 1969 by keyboardist Vincent Crane and drummer Carl Palmer, both alumni of The Crazy World of Arthur Brown. The band rose to prominence in the 1970s with their distinctive blend of progressive rock, hard rock, and soulful influences, scoring hits such as “Tomorrow Night” and “Devil’s Answer.”
After several lineup changes and a period of inactivity, Atomic Rooster experienced a revival in the 21st century. Since 2016, the band has been active again, featuring a lineup of original members and new musicians who keep the spirit of the band alive. Led by guitarist and vocalist Pete French—who was also part of the band in the 1970s—Atomic Rooster now delivers energetic live shows that showcase classics from their rich catalogue, while also making room for new material.
Today’s Atomic Rooster remains true to their roots: powerful Hammond organ parts, raw vocals, and a solid rhythm section are still at the heart of their sound. The band regularly performs across Europe and the UK, captivating both longtime fans and new audiences with their timeless, dynamic rock.

SLOMOSA
SLOMOSA’s music is a powerful fusion of stoner rock, grunge and punk, deeply influenced by the dramatic Norwegian landscape. Their sound is defined by thick, fuzz-laden guitar riffs that evoke the vastness of tundra and mountain, underpinned by a driving, groove-oriented rhythm section. The band’s approach to songwriting balances raw energy with melodic sensibility: massive walls of distortion give way to valleys of memorable hooks and atmospheric passages.
​
Vocally, SLOMOSA alternates between gritty, impassioned delivery and more melodic, introspective moments, reflecting both the intensity and emotional depth of their music. Their arrangements often feature dynamic shifts—sudden tempo changes, explosive choruses, and unexpected breakdowns—that keep listeners engaged and mirror the unpredictability of nature itself.

​
On their album Tundra Rock, the band further explores atmospheric textures and melodic layers, introducing darker tones and more nuanced songwriting. Songs like “Cabin Fever” and “Battling Guns” showcase their ability to blend crushing riffs with thought-provoking lyrics, while tracks such as “MJ” and “Dune” highlight their willingness to experiment with groove, rhythm and genre boundaries.

Their acclaimed debut Tales of the Wicked West (2016) and follow-up Madness Is Too Pure (2018) established them as innovators in the psych rock scene, leading to tours across Europe and appearances at major festivals like Freak Valley and Desertfest Berlin. After a creative pause, MaidaVale returned with Sun Dog (2023), a bold and experimental album released on their own label, Silver Dagger Records.

LYDSYN
Lydsyn’s sound is raw and stripped down to the essentials: guitar, bass, drums and a single vocal. Their music is rooted in classic hard rock, with a strong emphasis on powerful riffs, driving rhythms and a no-frills approach. The fuzz pedal is a central element, delivering thick, saturated guitar tones that harken back to the golden age of 1970s rock.
While there are echoes of Lorenzen’s earlier work with Baby Woodrose, Lydsyn leans more towards hard rock than psychedelia, focusing on directness and energy rather than extended jams or trippy soundscapes.
​
The band’s arrangements are tight and punchy, with songs that cut straight to the core—there’s little ornamentation, just pure rock energy. Lorenzen’s vocals are gritty and expressive, perfectly complementing the band’s muscular sound. The music often features catchy hooks and memorable choruses, making it both accessible and impactful.

The group’s sound is shaped by expressive musicianship: intricate guitar work, lush vintage keyboards, dynamic bass lines and inventive drumming.
​
Needlepoint’s compositions are rich and colourful, featuring shifting time signatures, melodic focus and seamless transitions between vocal and instrumental passages. Their arrangements incorporate a wide palette of classic instruments, creating a nostalgic yet fresh atmosphere reminiscent of 1970s progressive and psychedelic rock.

POTHAMUS
Happy to have these guys back after 6 years, they are more than ready to lift you up to a higher level on Friday.
​
Formed in Mechelen (BE) in 2013, Pothamus have carved out a reputation as ritualistic sludge-metal juggernauts, blending hypnotic riffs, tribal percussion, and crushing bass into transcendental soundscapes. Their debut album Raya (2020, Consouling Sounds) earned critical acclaim and propelled the trio—Mattias M. Van Hulle, Michael Lombarts, and Sam Coussens—onto prestigious stages across Belgium and international festivals like ArcTanGent, ESNS, and Motocultor. Returning with their highly anticipated second album Abur, Pothamus continue their quest for meaning, weaving eastern philosophy and western esotericism into immersive, primal compositions. To experience Pothamus is to surrender to a maelstrom of music and metaphysics—a cathartic journey beyond the ordinary.

Together, they blend traditional instruments with modern techniques to create a vibrant, danceable global groove.
Their sound is psychedelic, spiritual and rhythmically driven, often enhanced by dub effects and rich, layered arrangements.

TSCHAIKA 21/16
Have you seen three freaks? A tall one with a flute, a short guy with a light and one with a burning beard? What are they doing you might ask? Well…
Stoner, math rock, instrumental with horns and vocals…. and each time it gets more complex, more sophisticated in sound, more melodic, more driving, more versatile, more vocals, more trumpets, more, MORE…
​
ROTOR fans will love them, because in Tschaika 21/16 Rotor guitarist Tim goes one step further. The guitar always remains in the spotlight of attention.
​
In addition, Onkel, one of the capital’s most accomplished drummers and percussion masters, is allowed to let off steam and get involved.
​
On top of that, Sören, who otherwise plays “on the side” in the orchestra of the Berlin Konzerthaus, contributes wind instruments galore.
​
TSCHAIKA 21/16 is complete musically freedom and funny. Funny without using words.
BIKINI BEACH
Voracious caterpillars and beautiful butterflies. Fuzzy riffs and sugar-sweet melodies. Bikini Beach focus on contrasts on their new album. “Cursed” is album number seven by the border crossers from Lake Constance. Singer and guitarist Nils Hagstrom and bassist Charlotte Love live in Constance, while drummer Flip comes from nearby Switzerland.
“Everything has been cursed since 2020,” says the band, explaining the album title. “When we were in the studio for our fifth album “Atoll”, the coronavirus pandemic had just started. This not only completely overshadowed the release and the upcoming tours, but also brought with it a lot of disaster, fear and chaos. Not even two years later, the war broke out in Europe and is still going on. I wonder what other shit is coming our way?”
In 2025, Bikini Beach sound gloomier than ever. No wonder, with all the shit going on around us. The lyrics are about very personal problems or anger at the situation as a whole. The planet is going to the dogs, Nazis and populists are celebrating election victories and bombs and cruise missiles are flying in the neighborhood. “We are aware that, on the one hand, we live in a super privileged society, but at the same time we are sometimes simply stunned by current events,” says the band.
May The Fuzz Be With You
Nevertheless, there is this wonderful music. Guitarist Nils, bassist Charlotte and drummer Flip take us by the hand and pull us into
the furthest corner of the rabbit hole. Where the carrots are blue, the floor glows and the dandelion leaves taste like marzipan. Wonderfully scratchy lo-fi sound, cultivated slacker attitude. With a pinch of surf and psychedelic. The best sixties garage sound from the hit factory of Fuzztones or Miracle Workers. But the fuzz darlings from Constance have nothing to do with the heroes of the Eighties.
“We actually didn't know these bands until recently,” says Nils about the roots of Bikini Beach. “There's actually no connection to the Eighties or the Seventies. They were only oriented towards the sixties, like us. Our roots go back to the early albums by Ty Segall, Thee oh Sees, sixties garage like Them, Link Wray, or quite simply the Beatles. Sometimes classic black metal licks, Joy Division vibes or Nirvana-esque riffs creep in.”

GROS COEUR
Gros Coeur is a Belgian psych rock band from Liège, formed in 2021. Their music is a vibrant fusion of tropical psychedelia, improvisation and genre-bending experimentation.

GROS COEUR’s songs often feature long, evolving structures that break away from traditional rock formats, blending hypnotic grooves with bursts of carnival-like energy.

FEEDY
A manic mix of noiserock, postrock, stoner and jazzcore.
The Feedy sound is characterised by rapid shifts between loud volumes, hard riffs and harsh vocals, contrasted with loving, atmospheric pads, warm moments and piano patterns. Spontaneous cuts and wild breaks are followed by expansive atmospheric structures. They are constantly working on building their own musical identity. It’s schizophrenic.
We are inspired by bands like Godspeed, Neurosis, Radiohead, and The Ocean.
In 2019, the Feedy (s/t.) EP was released,
and in 2024, the debut album Xxn Vldz followed
HURACAN
Huracán is not your typical deliberately paced post-metal offering. With its razor-sharp riffs, propulsive drumming and psych-rooted vocals, treads skilfully across substantial, rugged grounds rumbling with echoes that recall bands ranging from The Ocean to Pelican to Pallbearer. Pure madness or genius, virtuosity or schizophrenia or all of the above? Who knows but there’s little doubt that this hurricane will wreck havoc, so consider yourselves warned!
​
“Huracan are raw, heavy, and play the unexpected. That which you didn't know you needed”
WASTE
WASTE has made a striking impression on the Belgian music scene, with critics consistently highlighting the band’s raw energy, intense live performances and unique blend of experimental noise and dark (post-)punk. WASTE’s sound is a powerful cocktail of manic vocal outbursts, pounding drums and searing guitar lines, all delivered with an unrelenting sense of urgency and emotion.
Their live shows are described as electrifying and chaotic, often bordering on destructive, with the band known to almost literally tear down the stage and whip audiences into frenzied mosh pits. The frontman’s presence is particularly noted—at times seeming possessed, channelling a wild, almost demonic energy that captivates and energizes the crowd. The band’s craft lies not just in making noise, but in captivating and moving their audience, turning every performance into an unforgettable experience.

AUFHEBUNG
A Brussels-based post-metal band, founded in 2020. Their debut album ‘Chasms’ (2021) introduced a sound that fuses heavy riffs with atmospheric calm. Known for intense live shows and a passionate audience, the band draws from post-rock, doom, and progressive influences to create cinematic, reflective music. Their next album, ‘LUCHTBEGRAFENIS’, is set for release in 2026.
Slow, sludgy riffs and screeching guitars meet melancholic harmonies and dissonant drones—beauty within chaos.
​
​
THE MOONDIG
The Moondig is a Belgian psychedelic rock band renowned for their fusion of catchy melodies and mind-bending sounds. With releases like the album Rubidium, they have carved out a place in the underground music scene, skilfully weaving elements of nature and science—such as rubidium, an element found in chemistry and nuclear medicine—into their artistic vision.
The band’s music is rooted in psychedelic rock, featuring atmospheric soundscapes and experimental textures. The Moondig stands out by blending melodic, accessible songs with more complex, mind-altering passages, creating a unique and immersive listening experience.
Scientific and natural motifs are often present in their work. This is exemplified by their album Rubidium, which references the element rubidium and its biological and medical applications.
