Louisville-by-way-of-NYC indie rockers Antietam flew to Austin to play four — yes, four — sets. Guitarist/singer Tara Key has branched out into solo albums, but as she explains, Antietam never broke up, even during a 10-year gap between albums. Their new album, Opus Mixtum, is now out on Carrot Top. Here, Tara provides a history of the band and her own musical influences. — Robin Cook
