Bobby Hutcherson's debut album is a masterpiece of "new thing" avant-garde jazz, not really free but way beyond standard hard bop. Dialogue boasts an all-star lineup of hot young post-boppers -- trumpeter Freddie Hubbard, woodwind player Sam Rivers, pianist Andrew Hill, bassist Richard Davis, and drummer Joe Chambers -- and a set of imaginative compositions by either Hill or Chambers that frequently push the ensemble into uncharted territory.
