Herbie Hancock (b. 1940), is an outstanding jazz piano player. In 1973 he created a new direction for jazz, influenced by James Brown and Sly Stone. The album was Head Hunters. It had four long, outstanding tracks, Chameleon, Sly, Vein Melter and a re-working of Watermelon Man. I discovered Head Hunters in about 1976 and fell in love with it. In particular I loved the full 15 minute Chameleon - the bass line remains my favourite non-reggae bassline. Easily found and great to listen to.
