I love this thread and will certianly post more tonight. Just for something that has not been mentioned though:
Miles Davis - The Cellar Door Sessions 1970
These mythical, Washington, DC December dates, released for the first in this impressive six-CD compilation, are an extension of Miles Davis's fusion LP, Live-Evil. The crew includes: keyboardist Keith Jarrett, drummer Jack DeJohnette, bassist Michael Henderson , percussionist Airto Moreira, saxophonist Gary Bartz, and guitarist John McLaughlin (featured only on some of the nights).
