Jerry Garcia in front of the Grateful Dead's Infamous Wall of Sound. The Wall of Sound was an enormous public address system designed specifically for the Grateful Dead’s live performances in 1974. It was the creation of audio engineer Owsley “Bear” Stanley. The Grateful Dead gave the sneak peek of the Wall of Sound on February 9, 1973 at Stanford University’s Maples Pavilion but it was on March 23, 1974 when they debuted the completed system during their tour stop at the Cow Palace in Daly City, California. Weighed over 70 tons, comprise dozens and then hundreds of amps, speakers, subwoofers, and tweeters, stand over three-stories tall and stretch nearly 100 feet wide. Its name could only be the “Wall of Sound”.
