Album: Various artists, Warp 20 (Unheard), (Warp)

Boards of Canada’s woozy one-loop lullaby “Seven Forty Seven”; Autechre’s approachable acid groover “Oval Moon”; the arpeggio squall of Clark’s “Rattlesnake”; the melodic techno-warble of Plaid’s “Dett”; Broadcast’s ever so slightly menacing cover of the Nico song “Sixty Forty”: when the music that it didn’t previously release is as good as it is on this, the third and most desirable of Warp’s 20th anniversary CD compilations, you know a record label has an embarrassment of riches. May the next 20 be as varied and fruitful.
