A sealed, unlabeled box sat undisturbed for decades on a shelf in the Grateful Dead’s San Rafael tape vault on Front Street, its contents an enduring mystery, even to those few with access to the vault. All David Lemieux knew about that box when he became the Dead’s archivist was that it contained tapes belonging to Bear—Owsley Stanley, the Dead’s first soundman and architect of the Wall of Sound. Even in the Dead Heads’ Holy of Holies, the taped-up box was tantalizing. But this was Bear’s personal property, and so he didn’t touch the box out of an abiding respect for the elder luminary of sound. Bear’s archive of Sonic Journal recordings had been kept safe for him for years within the Grateful Dead’s vault—over 1,300 reels of tape stored in heavy-duty cartons like old banana boxes. At any time, David could have popped the tops and explored them to his archivist heart's content. But they were off-limits without the nod from Bear.
