New Maps of Hell is Bad Religion's fourteenth full-length studio album (twentieth release overall), which was released on July 10, 2007. It celebrates the 25th anniversary of their first album How Could Hell Be Any Worse?, although the band had been around for twenty-eight years. The title is something of a departure for the band, in the sense that most Bad Religion albums have an eponymous title track, except How Could Hell Be Any Worse?, Into the Unknown, The Process of Belief and The Dissent of Man. The title may refer to a book on Science Fiction history by Kingsley Amis published in 1961. Guitarist Brett Gurewitz stated "We all liked the concept of maps, because we are exploring new material on this record, both musically and topically."
