UK duo Spaceheads have released 7 albums on such labels as Merge, BiP_HOp, Pandemonium Rdz. Andy Diagram (trumpet) and Richard Harrison (drums), take their unique sound, based on live trumpet loops, drums and electronics, to greater sonic extremes.
Lazy grooves and thick harmonised trumpet chords; sleazy deep beat brass and crushed up metallic drumbeats. Spaceheads mix the raw emotional sound of breath with the banging of wood on skin, and push it through the blips, crackle and distortion of pixelated electronic noise.
