One of the Grateful Dead's few hits, "Truckin'," like their other 1970 hit, "Casey Jones," fel victim to censorship due to the overt cocaine reference. The song is a virtual travelogue, taking in the changing San Francisco street scene, as well as the band's touring experiences. Their much-publicized New Orleans bust is well documented here, but with more of a sense of whimsy than regret. Musically, the song shines with a straight-ahead blues/boogie feel that never lets up. This is crossed with the band's excellent harmony vocals, and Bob Weir's strong lead vocals. The song admonishes the hippie culture on one hand to cool out, but there is also an underlying zeal to keep doing what they're doing to change their world. A great statement, it also ends the fabulous American Beauty album with style and energy.
