Jamaaladeen Tacuma (born Rudy McDaniel; June 11, 1956) is an American free jazz bassist born in Hempstead, New York. He was a bandleader on the Gramavision label and worked with Ornette Coleman during the 1970s and 1980s, mostly in Coleman's Prime Time band.
Tacuma showcased a unique style of avant-garde jazz on Coleman's 1982 album Of Human Feelings, and became widely viewed as one of the most distinctive bassists since Jaco Pastorius. He formed his own group, and recorded albums that incorporated commercially accessible melodies while retaining Prime Time's elaborate harmonies.
