Brian Douglas Wilson is an American musician, singer, songwriter, and record producer who co-founded the Beach Boys. Often called a genius for his novel approaches to pop composition, extraordinary musical aptitude, and mastery of recording techniques, he is widely acknowledged as one of the most innovative and significant songwriters of the 20th century. His best-known work is distinguished for its high production values, complex harmonies and orchestrations, layered vocals, and introspective or ingenuous themes. Wilson is also known for his formerly high-ranged singing and for his lifelong struggles with mental illness.

The Beach Boys are an American rock band formed in Hawthorne, California, in 1961. The group's original lineup consisted of brothers Brian, Dennis, and Carl Wilson, their cousin Mike Love, and friend Al Jardine. Distinguished by their vocal harmonies, adolescent-oriented lyrics, and musical ingenuity, they are one of the most influential acts of the rock era. They drew on the music of older pop vocal groups, 1950s rock and roll, and black R&B to create their unique sound. Under Brian's direction, they often incorporated classical or jazz elements and unconventional recording techniques in innovative ways.
