On August 17, 1969, Grace Slick and the Jefferson Airplane took the stage at the Woodstock Music and Art Fair. It was 8 o'clock Sunday morning, in theory the final day of the music festival that changed everything, but the Airplane was really the final act of Saturday night. After a break of several hours, the Sunday lineup resumed with Joe Cocker and the music played until Jimi Hendrix finally sent everybody home about 11 a.m. on Monday morning.
The summer of 1969 began, of course, with Hendrix and dozens of other acts warming up for Woodstock in the biggest rock festival to ever take place in the city limits of Los Angeles. I've posted several times about Newport 69 at the Devonshire Downs fairgrounds in Northridge, June 20-22, 1969.
