Following the evolution in form and approach of composer and tenor saxophonist Wayne Shorter from his 1966 Blue Note album Adam's Apple with Hancock, Workman and Chambers (including a pre-Miles "Footprints") to the 1969 Weather Report precursor Super Nova with John McLaughlin, Sonny Sharock, Miroslav Vitous, Chick Corea, and Jack DeJohnette.

Two live recordings from Miles Davis in the 1960s, first from Stockholm in 1967 with the classic 60s quintet of Miles, Wayne Shorter, Herbie Hancock, Ron Carter and Tony Williams; then two years later also in Stockholm with the "Lost Quintet" of Miles, Wayne Shorter, Chick Corea, Dave Holland and Jack DeJohnette, pushing new directions with tracks including "Bitches Brew".
