This Dick's Picks volume, which presents excerpts of the Dead's March 23, 1974 show at the Cow Palace, is not only historic but a hot show to boot! First, the history: this concert marked the first appearance of the famous (or infamous, depending on which Deadhead you ask) Wall of Sound concert PA, with the crystal-clear sound to show for it; it also features the debut of two songs, "Cassidy" and "Scarlet Begonias," that were to become staples of the band's repertoire.
