Brian Douglas Wilson (born June 20, 1942) is an American musician, singer, songwriter, and record producer who co-founded the Beach Boys. After signing with Capitol Records in 1962, Wilson wrote or co-wrote more than two dozen Top 40 hits for the group. In addition to his lifelong struggles with mental illness, Wilson is known for his unorthodox approaches to pop composition and mastery of recording techniques. He is often referred to as a "genius" and is widely acknowledged as one of the most innovative and significant songwriters of the late 20th century.
The Beach Boys were formed by Wilson with his brothers Carl and Dennis, their cousin Mike Love, and friend Al Jardine. Brian, who grew up influenced by 1950s rock and roll and jazz-based vocal groups, originally functioned as the band's songwriter, producer, co-lead vocalist, bassist, keyboardist, and de facto leader. In 1965, he suffered a nervous breakdown and stopped touring with the group, which led to more personal work such as Pet Sounds (1966) and the unfinished Smile. As his mental health deteriorated, his contributions to the band diminished, and over the next decade, he was reputed for his reclusive lifestyle and substance abuse. Following a court-ordered removal from the care of psychologist Eugene Landy, Wilson started receiving conventional medical treatment, and in the late 1990s, he began performing and recording consistently as a solo artist. He remains a member of the Beach Boys' corporation, Brother Records Inc.
