Over the past 20 years, Warp Records has been a driving force behind avant-garde electronic music and forward-thinking indie rock, providing a home for artists such as Aphex Twin, Boards of Canada, Squarepusher, and many more. Tonight, some of the label’s best and brightest celebrate its history. Jittery avant-rock supergroup Battles play their only U.S. date this year and preview new material; Liquid Liquefied dance rockers !!! will attempt to live up to the hyperbole of their name; and in between, Warp’s formidable legion of DJs will pay tribute to the label’s electronic past. With Flying Lotus and Pivot.
