On this episode, Marc talks with Brian Anderson, author of "Loud and Clear: The Grateful Dead’s Wall of Sound and the Quest for Audio Perfection," published in June of 2025. It's a detailed and compelling tale of how the Grateful Dead, over the first decade of their existence, continually created and expanded their own sound system into a gigantic tower of speakers known as the Wall of Sound. Scores of techs, roadies, and other fascinating figures worked on this monstrous array of gear, which delivered clear, almost mystical sound throughout the venues to which the Dead hauled it.

As Brian writes, "Our world has been radically shaped by the Dead, regardless of one's own relationship with the band. And their fabled PA of the early 70s is perhaps the most striking example of that outsized influence."
