I am not a professional commentator by any means. but i think this is a great album. the personnel playing the tracks are professionals of great virtuousity and impeccable technique. the music swings, its is rythmic, it is melodic and the improvisation is of the highest order. i stumbled upon it on youtube and im glad i did. Freddie Hubbard , Jim Hall , Plilly joe Jones, Percy Heath and Bill Evans. All at the top of their game.
