For me, the words “Wall of Sound” conjure up memories of the good ol’ Grateful Dead.
The year is
1974 and the Dead’s popularity as a live act has grown immensely. When they started out, it was gigs in ballrooms and small theaters. With popularity came arenas and stadium shows. The Dead, always conscious of their fans, responded by building a sound system that was hard to believe.
After years of research and experimenting, the Dead’s tech team, Owsley Stanley, Dan Healy, Rob Wickersham, Bob Mathews came up with a sound system that had 641 speakers , 48 amps, 11 channels and 54 tweeters. The whole thing weighed about 72 tons and it took five trucks to tote the equipment around. It put out around 26,000 watts of pure sound. The Wall of Sound did put a huge strain on the band’s resources and was only used in 37 shows over 7 month period. You don't have to be a Deadhead to appreciate the quality of music that a system this powerful could produce . Some of you fellow noders who are in the music business might appreciate the following breakdown of the Wall of Sound.
