Grateful Dead HQ dug into the band’s summer ’89 tour for this week’s All The Years Live pro-shot video, revisiting a vivacious, first-set “Cumberland Blues” from Wisconsin’s beloved Alpine Valley.

“From one of the Grateful Dead’s first home videos, Downhill From Here, this is the Dead at a later-era peak,” exaplains GD archivist/legacy manager David Lemieux. “‘Cumberland Blues’ was a song that always seemed to be played well, and when they nailed it perfectly, as they do here, it’s a six-man unit running at breakneck speed, acting as one unified force.”

On a previous edition of All The Years Live, Lemieux and company also showcased the “Uncle John’s Band” from this 7/17/89 outing.
