A must for a Stone fan, I think. Catches the band in one of the crucial moments of its career. The brand new Beggars Banquet material fresh and raw in their hands, Brian Jones´s last performance (only musically nice moment is the slide in "No Expectations"), Jagger is really topping his game, I think the most remarkable performance he has ever done; looking like Turner in Performance and with absolute self-control and self-secure... and Keith just looks cool
Surely not their best performance, the band is seemingly in rust, but still they are damn great... magical and strong. (Always hyped Who performance is secondary to them).
Of course, Circus is also a nice document of the special atmosphere of the time, plus the superjam of Lennon, Clapton, Keith and Mitch Mitchell is a sight in itself.
