20/20 is the 15th studio album by the American rock band the Beach Boys, released February 10, 1969 on Capitol Records. The LP was named for being their 20th overall release when factoring in live albums and compilations. Much of 20/20 consists of outtakes from earlier albums. It reached number 3 on UK record charts and number 68 in the U.S. Brian Wilson was absent during most of the album's recording after admitting himself into a psychiatric hospital, requiring brothers Carl and Dennis to retrieve several outtakes he had recorded years earlier. While Brian does not appear on the front cover, the inner gatefold of the original vinyl release features him alone, behind an eye examination chart.

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.
