The Electric Kool-Aid Acid Test by Tom Wolfe. It's about Ken Kesey's Merry Pranksters and their journey across the country and the Grateful Dead and all sorts of 60s counterculture icons. I guess it's being turned into a movie next year but who knows how that will turn out.

and if you are a Doors fan No One Here Gets Out Alive by Jerry Sugerman is phenomenal. I'm not big on biographies but that one is fantastic.
