Van Halen is an American hard rock band formed in Pasadena, California, in 1972. Its 1978 debut album, Van Halen—featuring guitarist Eddie Van Halen, vocalist David Lee Roth, drummer Alex Van Halen, and bassist Michael Anthony—is widely considered to be among the most "original" and "revolutionary" albums to "change rock and roll. br 1984 (released on January 9, 1984) was their commercial pinnacle. Recorded at Eddie Van Halen's newly-built 5150 Studios, the album featured keyboards, which had only been used sporadically on previous albums. The lead single, "Jump", featured a synthesizer hook and anthemic lyrics, and became the band's first and only No. 1 pop hit, garnering them a Grammy nomination. Other singles included "Panama" (#13 U.S.), "I'll Wait" (also No. 13 U.S.), and "Hot for Teacher".br The album, however, was also a breaking point for the band. In the midst of the 1984 Tour the artistic and personal tensions among the musicians reached a fever pitch. Reasons for the breakup vary based on the band member interviewed, but were rooted in control of the band's sound and image. Roth was upset about Eddie playing music outside of Van Halen without checking with the band, and his alleged drug abuse that allegedly prevented the band from viable practices.br Sammy Hagar agreed to join in 1985 and also serve as a rhythm guitarist on stage to add to the Van Halen sound. The 1986 Van Halen album 5150 was a hit, becoming the band's first No. 1 album on the Billboard charts, driven by the keyboard-dominated singles "Why Can't This Be Love" (#3 U.S.), "Dreams", and "Love Walks In" (Top 30 U.S. To further introduce the new era for the band, a new Van Halen logo was put on the cover. The new logo retained elements of the original, but now the lines extending from either side of 'VH' wrapped around and formed a ring.br After years of speculation, Van Halen began a tour with Roth across North America in 2007 and into 2008. On December 26, 2011, Van Halen announced a tour for 2012, and released their first album in 14 years, A Different Kind of Truth, on February 7, 2012.
