Tensnake, Steve Bug and Atari Teenage Riot have also been confirmed for the festival in Austria.
Taking place at a medley of odd venues around the city of Graz (caves, a fortress, a man-made island, etc.), springfestival is a four-day conference and electronic music festival. DJs and live acts already announced include Isolee, Caribou, Jesse Rose and Kompakt's Michael Mayer. In addition to Andy Butler and co, this week's lineup announcement names Tensnake, Steve Bug, Sebastien Leger, Patrick Wolf and Joe Goddard of Hot Chip as new additions. Drum & bass imprint Hospitality Records will host their own showcase, with London Elektricity, Logistics, SP:MC and others in tow. For anyone seeking something a bit harder edged, Atari Teenage Riot will play live at the festival as well.
