Bill Graham kicked off his 1967 Summer Series with an incredible lineup at the Fillmore. Headlining the show were Rock and Roll's biggest new stars, the Jefferson Airplane whose album, Surrealistic Pillow, was climbing the American pop charts. Last on the bill behind Jazz guitarist Gabor Szabo was a relatively unknown guitar player named Jimi Hendrix.
"Jimi first came to San Francisco right after Monterey Pop. …He opened and then Gabor Szabo and then the Airplane. That was the first night. Afterward, the Airplane asked him if they could open the show. Jimi took the town by storm." Bill Graham, Bill Graham Presents: My Life Inside Rock and Out
