Shoun Shoun
No wave. No logic. Somewhere between art rock and electronica. Using broken technology to make very human moments, Annette’s songs take sharp, twisted routes making your feet move one way and your head in very much another. Stuttering drums, liquid sex bass, post punk squonk and sporadic noise constitute a sound like no other.
Z Machine
Instrumental jazz-prog with teeth from the southernmost depths of Wales, who blend the complex structures of prog rock with the fluid improvisation of jazz. Expect soaring ambient textures, off-kilter grooves and sometimes a few too many notes. Each song is a twisting turning ride on a dangerous beast - you won't know where you're going, but you won't want to get off!
Zenden Greenpurp
A psychedelic prog punk metal outfit pushing music to its limits through chaotic, shape-shifting compositions, theatrical and unpredictable vocals and fiercely intense live performances. Their captivatingly unhinged sound collides precision with madness, delivering a visceral live experience.
Venice Treacle
Groove-enhanced quirk punk, which sometimes disintegrates into deranged disco. Right-angled riffs and rapturous rhythms combine with lyrics that confront the End of the World (and ice worms) head on. Named after the world’s first branded pharmaceutical, VT provides an antidote to the modern crazy. Guitars clash, beautiful harmonies appear and disappear, a groove emerges, and will not let you go.

Appearances include HRH Prog, A New Day Festival, Nene Valley Rock Festival, and a landmark set at Bloodstock Open Air, featuring the world’s first jazz-fusion wall of death. Currently, Z Machine is preparing to return to the studio to record their second album, following the success of their debut release, Merging Worlds.
