Grateful Dead Live at Fillmore East on 1970-02-11

With Duane Allman and Fleetwood Mac's original guitar wizard Peter Green sitting in alongside Garcia and Weir, the Dead's journeys were epic this night. Add Gregg Allman on vocals and organ, his Allman Brothers bandmates, Love's Arthur Lee on percussion and Mick Fleetwood dancing wildly in the wings, and you have the most impressively telepathic party ever captured on a Dead bootleg. Chaotic? Sure, at points, and it's a shame that surviving tapes are spliced and incomplete. But the sound rings clear on an unusually bluesy "Dark Star," guitarists circling like wild dogs, sniffing each other out. Then it opens into the rare "Spanish Jam," one of the Dead's jazziest workouts (inspired by "Solea," the flamenco variation on Miles Davis' Sketches of Spain), and builds to a supernova, eventually collapsing into a mighty 33-minute workout on "Lovelight."
