Wayne Shorter's compositions helped define a new jazz style in the mid-'60s, merging some of the concentrated muscular force of hard bop with surprising intervals and often spacious melodies suspended over the beat. The result was a new kind of "cool," a mixture of restraint and freedom that created a striking contrast between Shorter's airy themes and his taut tenor solos and which invited creative play among the soloists and rhythm section. The band on this 1964 session is a quintessential Blue Note group of the period, combining Shorter's most frequent and effective collaborators. Trumpeter Freddie Hubbard, pianist Herbie Hancock, bassist Ron Carter, and drummer Elvin Jones merge their talents to create music that's at once secure and free flowing, sometimes managing to suggest tension and calm at the same time. --Stuart Broomer
