This double CD compilation has some great music built into it. It focuses more on the soul side of George Duke's solo career. That said, there is still plenty of fusion here. We generally land fusion under prog rock. His time in Frank Zappa's band would likely have landed this there, anyway. There is some killer music here. A few songs on the second disc include Stanley Clarke, too. If you like funky music, you will love this thing.
