This CD is a bit different than Connie Crothers' usual recordings. The improvisations by her quartet (with co-leader tenor saxophonist Lenny Popkin, bassist Cameron Brown, and drummer Carol Tristano) are mostly not based on the chord changes of standards, the individual performances are generally fairly brief (only three exceed four minutes), and the playing is quite advanced, almost avant-garde. As usual, the musicians listen closely to each other and Crothers and Popkin make for a compatible team, but this rather brief set is less appealing than normal and few of the cuts are particularly memorable. Worth picking up but not essential.
