Late soul legend Otis Redding's music catalog will be administered by Sony Music Publishing as part of a new deal announced ahead of the premiere tonight (5/20) of the Max documentary STAX: Soulsville, U.S.A.

Redding's estate (DBA Big O Holdings LLC) is overseen by the musician's widow, Zelma, who said, "For over 50 years I have been diligent to make sure Otis’ legacy remains relevant and recognizable around the world. I feel that the Sony Music Publishing team can assist my family in this never-ending effort." The deal is for the U.S. only.

Redding, dubbed the King of Soul, emerged in 1964 with the single "These Arms of Mine" and was quickly recognized as a transcendent singer and performer. He also penned the classic songs "Respect," "Hard to Handle" and "Try a Little Tenderness," and, with Booker T and the M.G.s guitarist Steve Cropper, co-wrote "(Sittin' on) the Dock of the Bay," which went to #1 shortly after Redding's 12/10/67 death in a Wisconsin plane crash.

"As one of the most significant songwriters of our lifetime, Otis Redding remains an American treasure," said SMP Chairman/CEO Jon Platt. "Otis' songs have shaped the cultural landscape across genres and generations, and it is a privilege to partner with the Redding family as stateside custodians of this singular music catalog."

Redding is featured prominently alongside contemporaries such as Sam & Dave and Isaac Hayes in STAX: Soulsville, U.S.A. A separate film from director Adam Rubenstein, Soul Sound '67, is also in the works about Redding's longtime backing band, the Bar-Kays, four members of which died in the same accident as Redding.
