Anthem of the Sun

One year after releasing their gritty, garage-rocking self-titled debut, the Grateful Dead returned with a massive evolutionary leap: the sprawling, psychedelic *Anthem of the Sun*. Outré epics like \"That\'s It for the Other One, Pts. I-IV\" alternate between acid-rock excursions and atonal avant-gardism inspired by keyboardist Tom Constanten\'s experimental background, while trippy tunes like “Alligator” get a good coating of grease from resident blues wailer Pigpen.
