In Pictures Of An Exhibitionist, Keith Emerson recalls the August Jam rock festival held Saturday, 10 August 1974 at the Charlotte Motor Speedway outside Charlotte, North Carolina. This reminded me of a friend who attended a rock festival in North Carolina… he says it was the July 4th weekend in either 1976 or 1977, he thinks in Winston-Salem… and, inebriated, remembers virtually nothing of the experience. Foghat and Black Oak Arkansas with Ruby Starr were on the bill. Otherwise zilch. Can anyone fill in details of stadium festivals that fit these limited criteria? Very curious about who and what my friend missed.
