Another great one has passed on. He has great work in his discography as mentioned, Hot Buttered Soul, Black Moses, Live at the Sahara Tahoe. But in my opinion, his genius (that's right genius), can be found in the primarily instrumental "Shaft" soundtrack that includes the Oscar winning "Theme from Shaft". If you don't own it, now is a good time to make that purchase. The music is timeless and sounds just as fresh, cool, and sophisiticated as it did back in 1971. Mr. Hayes composed the score for the movie and it became an instant classic. If you listen to it, it is intricate, creative and inspiring music. No movie soundtrack in the "R&B" "Soul" genre can touch it and few in the history of movie soundtracks. Rest in peace Mr. Hayes, there are none like you out there.
