This 1980 recording released for the first time -- "Formidable" from a 1959 session and five numbers from a 1963 
McLean set. While "Formidable" has a strong quintet (with altoist 
Jackie McLean, trumpeter 
Donald Byrd, pianist 
Walter Davis, bassist 
Paul Chambers, and drummer 
Pete La Roca), the 1963 session has the recording debut of drummer 
Tony Williams along with strong contributions from 
Byrd, pianist 
Herbie Hancock (then also near the beginning of his career), and bassist 
Butch Warren. The latter unit sticks to group originals by 
Byrd, 
Hancock, and 
McLean, and the music ranges from catchy funk and hard bop to strong hints of the avant-garde. ~ Scott Yanow
