Ever since Sonny Rollins' Way Out West was released in 1957, with Shelley Manne on drums and Ray Brown on bass, the saxophone-bass-drums line-up has been a popular vehicle in jazz, and especially in free jazz because it offers so much room for soloing, for dynamic interplay and especially for powerplaying without having to care for the arrangements needed to avoid chaos with a bigger band. He kept using the trio setting for many more outings to come, of which the most recommended ones are : Night At The Village Vanguard and Freedom Suite.
