From the Bill Graham FB page:
Recorded live, October 24–26 at Fillmore West-- "They may have had hits and media exposure, which probably caused them to burn out and become rapidly obsolete as the starry-eyed sixties gave way to the cynical seventies, but at their height, they were so much more than simple poster children for fashionable -and dispensable- hippyness. Jefferson Airplane was in fact perhaps the hardest-hitting acid band in Frisco, capable of belting out a raw and ragged sound that even the Grateful
and Quicksilver Messenger Silver, in all their jamming, couldn't equal. By 1969, Jefferson Airplane had an edge to rival the Doors and Iron Butterfly, which sat up nicely alongside their anthemic singles.
And Bless Its Pointed Little Head captured that edge and energy on vinyl. It's a proper, unfettered, warts-and-all live masterpiece that showcases not only the band's knack for anthemic tunes and the neat vocal interplay of Slick and fellow singer Marty Balin but also their ability to let loose, to improvise, and to rave it up. Everyone's a hero on Bless Its Pointed Little Head. Slick is at her best, taking her staple "Somebody to Love", for example, and turning it inside out as the band funks it up behind her, belting out some delirious rapping vocalizations like a crazed Southern gospel singer. The song is revved up, white-hot, yet tight and crisp, and the band delivers similar punchy moments of brilliance on Balin's staples "The Other Side of This Life", "It's No Secret" and "3/5's of a Mile in 10 Seconds". The 'Plane's other singer demonstrates just how underrated he is, particularly on an almost punkish version of "Plastic Fantastic Lover", where he shouts himself raw above a fierce garage beat."
