The Brian Wilson Band, also known as the Pet Sounds Band since 2025, is an American touring ensemble that served as the backing band for Beach Boys co-founder Brian Wilson from 1999 until his retirement in 2022. The band was largely drawn from the Los Angeles power-pop group the Wondermints, supplemented by Chicago-based session musicians who had recorded with Wilson on his 1998 solo album Imagination. Under the musical direction of keyboardist Darian Sahanaja, the ensemble accompanied Wilson on continuous international touring for over two decades, performing the complete Pet Sounds album live, staging the long-delayed premiere of SMiLE, and celebrating the 50th anniversary of Pet Sounds. Following Wilson's retirement and his death in June 2025, Beach Boys co-founder Al Jardine reassembled the band's core members in 2025 under the name the Pet Sounds Band to continue performing Wilson's music as a tribute.
