For nearly twenty years Tim Gane and Lætitia Sadier have expertly fashioned experimental indie-pop that deftly fuses 60s lounge, krautrock and whimsical European pop, to carve a musical niche all of their own. Not Music is their swansong, a bundle of previously unreleased material, created during sessions for last album Chemical Chords. Whether doing “quirky” on the xylophone-flecked ‘Two Finger Symphony’ or “post-rock” on the echoing wall of keyboard noise ‘Neon Beanbag’, their final offering is a fitting demonstration of the versatility and innovation that’s been delighting scores of listeners since 1991. So it’s with very heavy hearts we bid farewell to Stereolab: let’s hope it’s merely au revoir, eh?
