This studio LP was first released almost a decade after it was recorded. The first half features the 1967 Quintet (with Wayne Shorter on tenor and soprano, pianist Herbie Hancock, bassist Ron Carter, and drummer Tony Williams) performing three otherwise unknown Shorter compositions. The flip side finds Davis in 1968 leading the same group (with possibly Chick Corea and Dave Holland replacing Hancock and Carter) on two early fusion jams that look a bit toward Bitches Brew. Although not an essential set, this album fills in some gaps during Davis's transitional period from adventurous acoustic playing to early electric performances.
