Directed by D.A. Pennebaker, and filmed by Richard Leacock, Pennebaker, and other independent filmmakers, the film possesses a quality of nostalgia beyond the fact that it was made way back in 1967. Otis Redding shouts: “We all love each other, right?” But Otis is dead—along with Janis Joplin, Jimi Hendrix, and probably half the people who appear in the film. But where else can you hear “Feeling Groovy” or “California Dreaming” anymore?
