Perhaps the most bootlegged band in history (they were among the first to encourage fans to tape their shows), the Grateful Dead, whose studio output was spotty and sometimes haphazard, made their true mark on stage. And this humongous box - 73 discs encompassing 22 shows - underscores the group's gifts as a synergistic live unit.
Standout performances abound on concerts recorded in Rotterdam, London, Copenhagen, Dusseldorf and Paris, among other locales. While it's doubtful that even the most rabid fan could listen to all 22 shows in one sitting (how many hours is that, anyway?), spread out over weeks or months, this collection should yield many musical treasures.
