While the Masterworks albums show how this saxophonist changed jazz style forever, Trane was always open to the innovations of other artists. On albums like The Avant-Garde, he dove into the more tart-sounding experimentalist world of trumpeter Don Cherry. And on obscure sessions with his classic quartet, you can hear the saxophonist pushing his instrument and band to the limit, with crashing rhythms, forceful overblowing and feverish explorations of themes.
