Patient exploratory jamming that captures the very best of the early psychedelic Dead for one of the best live albums of all time - not just the hits performed in front of an audience, but an album who's liveness, the presence of performance, is what makes it what it is. Dark Star alone makes this a five-star album: the interplay between the band, listening, responding, building, and turning each others melodic and rhythmic ideas as they improvise their way through the (more structured than you'd think) segments of the peice is staggering. There's so much space in the music despite the number of instruments contributing to it. Through Dark Star > St Stephen > The Eleven they ratchet up the tension, go dark to dwell in some minor key modes, bring it back to a bright joyous major key, let the music dissipate, wrangle it back together for a verse, segue from song to song to keep it rolling. The album climaxes in the raunchy RnB rave up Lovelight, before the mournful dark blues of Death Don't Have No Mercy, which eventually dissolves into feedback, the controlled chaos of signal becoming noise becoming signal.
