And while their 12th album, Evolver, is built on the hybrid rock and rap-rock origins of the band, it strikes the listener as both surprisingly mellow and somewhat of an evolutionary departure from some of the their prior work, hence the irony tucked within the name of the album. Since that time, 311 has released 12 albums (three independent releases, seven major label releases, a live album, and an old-school compilation). The origins of the band began in the mid-to-late 80s, with several line-up changes and a few name changes before the band finally settled on the moniker 311 in the late 1980s (for those unfamiliar with the band, their name is taken from the universal police code for indecent exposure). 311 (pronounced 'Three-Eleven') is a band of five friends and musicians from Omaha, Nebraska.
