Battles is a quartet comprised of drummer John Stanier of Helmet and Tomahawk, guitarist/keyboardist Ian Williams of Don Caballero and Storm & Stress, guitarist David Konopka of Lynx, and avant solo musician Tyondai Braxton. All members bring their honed-in angular math skills of past glory to Battles. The Tras and EP C EPs were both released in June 2004 on Cold Sweat and Monitor respectively. The B EP followed on Dim Mak in September 2004. The Atlas EP followed in early 2007, followed in turn by the band's proper full-length debut, Mirrored, in May 2007. In 2010, Braxton announced he was leaving the band to pursue his own solo work while the rest of the group set to work on a new record as a trio. The following year, Battles released their second full-length album, Gloss Drop.
