There’s nothing that makes you feel old like an electronic music label turning 20, and that’s just what one of the most reliably underground labels of the last, well, 20 years is doing. Warp Records, the Sheffield based label that has brought us seminal releases from the likes of Aphex Twin, Autechre, Black Dog, The Orb, Squarepusher and Boards of Canada, whilst single handedly defining the sound of a generation of bleeps and beats artists, is now two decades old, and to celebrate they’re releasing a typically well designed box set on 25th September. Comprising of a series of 10″ vinyls, CDs and a beautifully produced book showcasing the label’s rich design history, Warp20 features new songs, older previously unreleased material from their artists, a personal selection by co-founder Steve Beckett and the top ten pieces voted for by Warp Records fans on Warp20.net.
