Fleetwood Mac's "Boston Live" is a pretty good set, even though it seems thrown together haphazardly compared to slicker live productions like the ABB's "Live at Fillmore East." Two different 25 minute jams over "Rattlesnake Shake" highlight both the live power of the original Mac lineup and the undisciplined mashup nature of this particular live production. Man, was Peter Green ever a monster player in 1970, howling banshee harmonics off of snarling open chords, that angry vibrato that seizes the note and throttles it an instant ahead of the beat like some kind of feral beast, and then he'd segueway into mellow bluesy turnarounds and comps, sweet as molasses. Danny Kirwan was riffing hard and steady on the rhythm guitar the whole set, and Jeremy Spencer was no slouch on his slide-drenched throwback numbers. Mick and Mac were at the very top of their game, with Mac even tossing in an epic six minute bass solo to close out the outro jam on "Green Manalishi."
