Brian Douglas Wilson (born June 20, 1942) is an American musician and the leader, lead vocalist, bassist and chief songwriter of the Beach Boys. Besides being their primary composer, he also functioned as the band's main producer and arranger. After signing with Capitol Records in mid-1962, Wilson wrote or co-wrote more than two dozen Top 40 hits for the Beach Boys.
In the mid-1960s, Wilson used his increasingly creative ambitions to compose and produce Pet Sounds, considered one of the greatest albums of all time. The intended follow up to Pet Sounds, Smile, was cancelled for various reasons, including Wilson's deteriorating mental health. Wilson's contributions to the Beach Boys diminished and his erratic behavior led to tensions with the band. After years of treatment and recuperation, he began a solo career in 1988 with Brian Wilson, the same year that he and the Beach Boys were inducted into the Rock and Roll Hall of Fame. Since then, he has toured for the first time in decades with a new band and released acclaimed albums, including a reworked version of Smile in 2004, for which Wilson won his first Grammy Award for "Mrs. O'Leary's Cow (Fire)" as Best Rock Instrumental.
