I know everyone here has at least heard/read about the festival, but despite having a poster of in my old bedroom at my dad's house of Jimi burning his guitar, I'd never seen or heard any of the performances.
It's a lot shorter than the Woodstock doc: not as many songs per performance (in fact, not even full songs in some cases such as Simon & Garfunkel) and not so much footage of the festival getting put together or the crowds (although there's a fair amount of shots of the spaced-out hippies). But it was fun seeing some of the shows. The Who, Hendrix, and Big Brother & Holding Company weren't big yet (well, the first two obviously were in the UK, not so much in the USA), and IMO Jimi and Janis were on much better form than at Woodstock.
Other highlights include the fervor around Ravi Shankar's performance and S&G. Lowlights were probably The Animals mk 2 (crappy violin-driven cover of Paint It Black) and Country Joe & The Fish (is there any 60s group that people care about less nowadays than f*ckin Country Joe?). I would've liked to see The Byrds, Buffalo Springfield (minus Neil, plus Crosby), Grateful Dead, or some of the blues guys like Eric Butterfield or Al Kooper. Some of that footage is probably in the extras on the rest of the boxset.
Anyway, it was fun to see some of this stuff after reading about it for so long. I'll sign off by leaving this Christgau essay that he did for Esquire at the time. God, he was such a smarmy f*ck even then, and also quite racist. ("Hendrix is a psychedelic Uncle Tom. Don’t believe me, believe Sam Silver of The East Village Other: “Jimi did a beautiful Spade routine.” Hendrix earned that capital S.")
