All-Time Greatest Rock Performance

To me this performance "Kashmir" by Led Zeppelin at the 1979 Knebworth Concert in London is the greatest rock performance of all time by anybody anytime, PERIOD! It combines the quality of the song itself with quality of the performance of the song and the charisma of the band individually and collectively driven by the late John Bonham's drums. The song itself is rather weighty and deep and gets into existentialist metaphors derived from a journey down a desolate road that never seems to end. Interestingly, I hold this opinion of this song despite not being a big Led Zeppelin fan. However, this entire performance blows me away. Go full-screen on this and crank up your speakers and enjoy!
