Widely considered one of the Grateful Dead's seminal performances, and certainly one of the very best of the universally acclaimed 1973 performing year, 6/10/73 is as synonymous with great Grateful Dead concerts as are 2/13/70, 8/27/72, and 5/8/77. There are few shows that deliver the goods to the extent of this concert, with its statement-opener of "Morning Dew," through lengthy workouts on "Bird Song," "Playing in the Band," "Here Comes Sunshine," "Eyes of the World," and an other-worldly "Dark Star." Add to this a nearly hour-long encore/third set featuring members of the Allman Brothers Band ( with whom the Dead shared the bill at RFK in 1973 ), and you have not only one of the most unique shows in Grateful Dead history, but also one of the most exciting, inspired and powerful performances of the Dead's entire career. Grateful Dead Productions are serving up the complete previously unreleased performance, with Plangent Processes tape restoration and speed correction, and mastering by Jeffrey Norman.
