For the latest iteration of their “All The Years Live” video series, Grateful Dead HQ has shared a pro-shot “Big Boss Man” from the band’s 6/16/90 gig Mountain View, Calif.

“A staple of the Pigpen-era Grateful Dead, ‘Big Boss Man’ departed the repertoire when Pigpen departed the stage in 1972,” said GD archivist/legacy manager David Lemieux of the recording. “Although it returned in 1981 for 15 performances over the next 15 years, it was sadly never incorporated into the setlist on a full time basis. This penultimate version features a gnarly lead vocal by Jerry.”
