Though the initial framework and a rudimentary form of the system was unveiled at Stanford University's Maples Pavilion on February 9, 1973 (every tweeter blew as the band began their first number), the Grateful Dead did not begin to tour with the full system until a year later. The completed Wall of Sound made its touring debut on March 23, 1974, at the Cow Palace in Daly City, California. A recording of the performance was released in 2002 as "Dick's Picks Volume 24".
