Universal Pulse is the tenth studio album by American rock band 311, released on July 19, 2011 on 311 Records/ATO Records. Like its predecessor, Uplifter, this album was produced by Bob Rock, who has produced or engineered albums by numerous notable acts, such as Metallica, Aerosmith, Motley Crue, Bon Jovi, The Cult, Our Lady Peace and The Offspring. Unlike previous albums where their record label requested that the drums be recorded at an alternate location, all tracks, including the drums, were recorded at the Hive Studio. To support the album, 311 invited Sublime with Rome to co-headline the 2011 Unity Tour, with special guests DJ Soulman and DJ Trichrome. The artwork was done by Sonny Kay. The album's first single "Sunset in July" was released on June 3, 2011. 311 (pronounced "three-eleven") is an American reggae/rock band from Omaha, Nebraska. The band was formed in 1988 by vocalist/rhythm 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. To date, 311 has released ten studio albums, one live album, four compilation albums, four EPs and four DVDs. After a series of independent releases, 311 was signed to Capricorn Records in 1992 and released the albums Music (1993) and Grassroots (1994) to moderate success. They achieved greater success with their 1995 triple platinum self-titled album, which reached #12 on the Billboard 200 on the strength of the singles "Down" and "All Mixed Up", the former of which topped the Billboard Hot Modern Rock Tracks in 1996. The band's next three albums, Transistor (1997), Soundsystem (1999) and From Chaos (2001), did not achieve the massive success of the self-titled album, though they were still successful, with the first going platinum and the last two going gold. Their 2004 compilation album Greatest Hits '93–'03 was also certified gold. The band's most recent studio album is 2011's Universal Pulse. As of 2011, 311 has sold over 8 million records worldwide.
