311 (pronounced "three-eleven") is an American rock band from Omaha, Nebraska. The band was formed in 1988 by vocalist/guitarist Nick Hexum, lead guitarist Jim Watson (who would later be replaced by Tim Mahoney), bassist Aaron "P-Nut" Wills and drummer Chad Sexton. In 1992, Doug "SA" Martinez joined to sing and provide turntables for 311's later albums, rounding out the current line-up. 311 is generally known as an alternative rock band, but it is also classified as rap rock, rap metal, funk rock, funk metal, reggae and jazz fusion. The band's name originates from the police code for indecent exposure in Omaha, Nebraska, after the original guitarist for the band was arrested for streaking. To date, 311 has released ten studio albums, one live album, four compilation albums, four EPs and four DVDs. As of 2011, 311 has sold over 8.5 million records in the US. They are currently working on a new album, which is due for release in 2013.
