Greg Osby and Sound Theatre is the debut studio album by saxophonist Greg Osby recorded in 1987 and released on the JMT label.

[1] The AllMusic review by Scott Yanow states, "The performances (mostly Osby originals) are complex, somewhat abrasive, and in the M-Base genre, swinging in their own funky fashion and following a different logic than bebop.

Osby plays quite well, and the music grows in interest with each listen".
