On this edition of Road Gang Radio, Jimmy Mac and Lindsay Lawler dive headfirst into rock ‘n’ roll lore with journalist and author Brian Anderson, whose new book Loud and Clear: The Grateful Dead’s Wall of Sound and the Quest for Audio Perfection captures one of the most ambitious—and insane—feats in live music history.

Towering over a hundred feet wide and as tall as a school bus is long, the Grateful Dead’s Wall of Sound wasn’t just loud—it was revolutionary. With obsessive detail and over 100 interviews with band members, tech wizards, and true Deadheads, Brian explores how the wall came to be, why it mattered, and how it nearly broke the band in the process.
