Rocky Mountain Grateful Dead Revue — Cervantes' Masterpiece Ballroom, 9 April 2021

A live concert recording from the Internet Archive's Live Music Archive, which holds only bands that have given permission to be recorded and traded. That permission is the whole basis of the collection. The Grateful Dead formally set aside a taper section behind the soundboard in 1984, legitimising what their audience was already doing, and the bands that inherited that audience inherited the policy with it — so these recordings exist because the artists wanted them to, not in spite of them. Rocky Mountain Grateful Dead Revue at Cervantes' Masterpiece Ballroom, 9 April 2021. The archive holds 4 recordings of this band. The setlist, the taper and the recording chain are not in the file name, and for this kind of recording they are what listeners most want to know.
