by Scott Yanow After four years mostly off of records, the innovative pianist/composer Andrew Hill re-emerged for this Freedom set, which has since been reissued on CD. The program is split between quintet numbers with altoist Lee Konitz (who doubles on soprano) and trumpeter Ted Curson, and quartet performances that showcase the somewhat forgotten altoist Robin Kenyatta. In addition, "Invitation," the one Hill nonoriginal, is taken as a spontaneous duet with Konitz. Although the music overall does not reach the heights of the pianist's earlier work for Blue Note (or his later sessions), there are enough surprising moments and thought-provoking solos to make this a release worth picking up by open-eared listeners.
