15 Big Ones is the twentieth studio album by the American rock band the Beach Boys, released on July 5, 1976, by Brother/Reprise. It includes a mix of original songs and renditions of rock 'n' roll and R&B standards. The LP was the band's first album with production credited solely to Brian Wilson since Pet Sounds (1966). As such, its release was accompanied by a controversial media campaign that declared his comeback as an active member of the Beach Boys' recording and touring group.
