You and Bloom - Tribal/percussive dual drum attack, with edited improvised ambient/soundscape laptop accompaniment. A bit like being kidnapped whilst on African safari, and then being rescued by Enya.
'You & Bloom' is David Morrison and Martin Chatterton. Both drummers sharing a passion for improvised electronic composition, in December 2006 they decided to start a project that combined the two. After a series of improvisations, sections of audio are pieced together forming a continual evolving soundscape, upon which dual drums are written.
Blue Spring - 'loudest band in Reading'. Think mclusky/sonic youth or a thousand minor celebrities being thrown into a wood chipper.

Ever changing/evolving lineup featuring upto ten musicians. Incorporating drums, percussion, electric guitar, strings and the audience. Incredible improv that needs to be experienced. Along the lines of godspeed & acid mothers temple
Bent Ohm - ben playing live breakcore/electro madness
