So many great suggestions with lots I need to check out. My faves (mixing DVDs and Albums)
The Who - Live at Leeds - All time best live Rock disc imho.
Rush - Exit Stage Left - Rush at their best imho. Neil going crazy and showing so much energy.
Peter Gabriel - Secret World - Manu Katche is great!
King Crimson - Live at Frejus 1982 - From Neil and Jack and Me concert DVD. Bruford is great as always and Adrian Belew is a monster Singing, playing insane guitar and lots of drumming from him too.
Mahavishnu Orch- Between Nothingness and Eternity - Not the best sound quality but Cobham shreds.
Jean Luc Ponty - Live 1978 - I had this on cassette and they wouldn't release it on CD until recently. I had to make a copy of the cassette to listen to because it was getting worn out. Casy Schurell is the drummer I think.
Bjork - Live at Cambridge 1998 - Electronic drums and programming from Mark Bell here, a concert masterpeice.
