5150

5150 (pronounced "fifty-one-fifty") is the seventh studio album by American rock band Van Halen. It was released on March 24, 1986, by Warner Bros. Records and was the first of four albums to be recorded with lead singer Sammy Hagar, who replaced David Lee Roth. The album was named after Eddie Van Halen's home studio, 5150, in turn named after a California law enforcement term for a mentally disturbed person (a reference to Section 5150 of the California Welfare and Institutions Code). The album hit number 1 on the Billboard 200 chart, surpassing the band's previous album, 1984, which had peaked at number 2 behind Michael Jackson's Thriller album, on which Eddie made a guest appearance.
