I want to recommend this band to all of you. They play very good Math rock. A bit like Animal Collective in my opinion.

"Battles is a quartet comprised of drummer John Stanier of Helmet, The Mark of Cain, and Tomahawk, guitarist/keyboardist Ian Williams of Don Caballero and Storm and Stress, guitarist David Konopka of Lynx, and avant solo musician Tyondai Braxton (who has recently collaborated with Prefuse 73). All members bring their finely honed instrumental skills of past glory to Battles. The Tras and EP C EPs were both released in June of 2004 on Cold Sweat and Monitor respectively. The B EP followed on Dim Mak in September of 2004. All three EPs were re-released as a two-disc set on Warp Records in early 2006."
