#350 Stevie Wonder, 'Music of My Mind' (1972)
To the casual observer, Stevie Wonder is a piano playing hit machine. But he’s so much more than that. He’s an innovator. He’s a musical genius, and I don’t use this term lightly. On most of his records, but this one in particular, Stevie Wonder plays every single note of every instrument (except for trombone on the first track and guitar on track 4). He was doing it well ahead of Prince.
