LOUD AND CLEAR: The Grateful Dead's Wall of Sound and the Quest for Audio Perfection

Story of the Grateful Dead's "Wall of Sound," an unprecedented and since-unparalleled speaker system that was as tall as a school bus is long and more than a hundred feet wide. The band's quest for roaring yet crystal-clear sound began after their formation in 1965, colliding with the '60s progressive social climate. 16 pages of photos, some in color.
