James Ford and Jas Shaw were already part of the experimental-electronic band Simian, but, with shared interest in electronic dance music, they wanted something more. So they left the original group to form the electronic-music duo Simian Mobile Disco. As DJs and producers, Ford and Shaw are also known for their remix work (together and individually) with groups like Arctic Monkeys, Muse and Florence and the Machine. Their first LP, the subtle but energetic Attack Decay Sustain Release, came out in 2007 and was very well received. Simian Mobile Disco have remained busy ever since: Their third album, Unpatterns (stream it below), was released earlier this year, and tomorrow night they bring their dance party to Webster Hall.
