I saw him in Houston in '72 or '73, Sly with the original Family Stone lineup (with Larry Graham ! !). Opened with 'Want to Take You Higher' for about 20 minutes, and plowed through most of his songs for the next two hours. The band was fabulous, but he was already involved with the dependencies that would rule for the majority of the rest of his life. I always remember that this show was great, but obviously something was a little 'off'. It was also easily the LOUDEST show I ever heard: I could've easily fired the Beretta alongside either ear and the only way I'd have known if went was the felt recoil, it was that loud.
The opener? Marc Bolan and T Rex, and Bolan was there . . . . but not present at all.
James Brown distilled R+B into the foundation of funk, and Sly ran with it and added rock with a Bay Area taste, and the book the two of them co-authored was used by Prince, Michael Jackson, Parliament/Funkadelic and so many others. Listen to 'Dance to the Music', the 'only ONE chord?' 'Everyday People', the huge-riff driven 'Sing a Simple Song', and the call of 'Stand' and there's one vital life force behind all of them and more: Sly Stone.
