My favourite of the lockdown era livestreams. The Lev Sessions and Red Rocks ones are great too, but Big Sur made "Mutilator Defeated At Last" click for me after I'd struggled with it for a while - those versions of 'Rogue Planet', 'Poor Queen' and 'Withered Hand' are so good, as is 'Gholü' and 'Gelatinous Cube'. The encore of Black Flag covers bang hard as shit too.
Also worth a mention are the bonus non-album Panther Rotate experiments at the start of the livestream; an interesting warm-up. Xtra Happy
