Phil Lesh Loved the Wall. The DRINKING Started in ’75.

In 1974, Phil Lesh watched the Grateful Dead build the most advanced sound system in rock history — and watched it shut the band down. He thought they might never start again.

The Wall of Sound debuted March 23, 1974 at the Cow Palace. Forty feet high, seventy feet wide, 604 speakers, 26,400 watts, fifty-five McIntosh MC-2300 amplifiers. Owsley “Bear” Stanley’s vision realized — every seat in the house, perfect sound. Crystal clear at any volume. Phil Lesh’s bass, for the first time, was no longer buried in the low end. Each string had its own dedicated channel. The bass was a lead voice.

Then the system collapsed under its own weight. Seventy-five tons of equipment. Four trucks. A crew of sixteen. Two complete stages leapfrogging each other. Half a million dollars of overhead before a single note. On May 12, 1974 in Reno, a 1,200-pound speaker cluster started swaying in the wind above Bill Kreutzmann’s drum kit. The system was unstable. It was beautiful. It was also unsustainable.

October ’74. Five nights at Winterland. The shows that became The Grateful Dead Movie. Jerry Garcia wanted a break — he had the Jerry Garcia Band. Bob Weir had projects. Mickey Hart had returned. Phil Lesh had nothing else. He’d helped build the Dead. Without it, he had no future. The drinking started in 1975.

This is the 1974 hiatus told from the perspective of the only member who didn’t have an exit ramp.
