This encounter between Chick Corea (sticking to acoustic piano), tenor saxophonist Michael Brecker, bassist Eddie Gomez, and drummer Steve Gadd lives up to expectations. The original program featured three lengthy "Quartet" pieces including sections dedicated to Duke Ellington and John Coltrane. The CD reissue adds four briefer pieces that were previously unissued, including an unaccompanied Brecker workout on "Confirmation" that would be perfect for "blindfold" tests. This blowing date is highly recommended for all true jazz fans.
