After the Beach Boys' formation, Murry became the group's business manager, co-producer, and publisher in the early part of their career. Known as a domineering and manipulative man, Murry was a tough negotiator on the band's behalf, organizing a contract signing with Capitol Records. Around June 1962, Murry and Brian established the music publishing company Sea of Tunes to safeguard Brian's compositions. The Beach Boys' first few records credited Capitol A&R director Nik Venet as producer. After April 1963, Capitol allowed Brian to produce their records himself, following Murry's insistence. Murry also introduced Brian to Roger Christian, who became Brian's writing partner for the band's car songs.
