Sister act Tegan and Sara have a new single titled 'Hell' from their sixth studio album, 'Sainthood' (set to release Oct. 27). A record about "obsession with romantic ideals," this is the first album the duo have written together, with Death Cab for Cutie's guitarist Chris Walla and Howard Redekopp producing the album. Tegan and Sara worked with Walla on 'The Con' and Redekopp on 'So Jealous,' which the sisters deem as their two best albums, as well as fan favorites. Be sure to listen to their new single 'Hell' on AOL Radio's Brand New Indie station, and check out their upcoming tour dates.
