Just a sample of Sly at Woodstock.
In 1967 (coulda been 68?) my older sister drove me and a couple of friends to the Electric Circus (we had fake id's) and we danced to Sly & Family Stone. That was my first full blown 'concert' event, though it was actually an intimate venue. The place was cazy with lighting and odd spaces and I got a huge dose of this high energy in-your-face joy.
