Query: A low point from a great band

Anyone who is familiar with the Grateful Dead knows that the real deal is live material. That being said, the Dead did release some great studio titles (Workingman's, American Beauty, Mars Hotel). This, however, is not one of them. In fact, I would say this is the nadir of 1970s era Dead, a period generally acknowledged as their most prolific and accomplished. While some of the material is strong ("Shakedown", "Fire"), most of the rest is just plain awful. The execution is competent, but annoyingly garnished with a "disco" sheen that is enough to make you either laugh or cringe. Do NOT play this disc to the uninitiated-- they may never get any further!
