To me, the ace in the hole is Tony Williams. His inclusion was a stroke of genius that makes the date more than it would have been with any other drummer Hill had associated with thus far (though Roy Haynes & Elvin Jones both brought something special to his music, Haynes in particular). I go back & forth re: Kenny Dorham, though. On the one hand her serves the music in his own way, but in another I can't help but imagine what it would have been with Woody Shaw in his place.
