Whenever these discussions are had, I never see Sly Stone's name brought up. :slystonesmiling:
Sly was Prince before Prince and even Stevie before Stevie. Sly influenced a whole slew of artists.
His voice had the bravado somewhat like Ray Charles
He plays keyboards, bass, guitar, piano, harmonica, drums (he was 1 of the 1st to use the drum machine on an album!), organ and vocoder.
He wrote, produced and arranged all of his own songs
And he played a huge role in the contribution in making Funk what it was, he did Gospel and Doo-Wop before that and his music is the definition of Soul.
