Ummagumma [Record One] and/or Live at Pompeii's bootleg release
Magma Live (1975) - the bass and drum work on Kohntark by Paganottii/Vander is possibly the best rhythm section live performance I've ever heard
John Coltrane - Live at the Village Vanguard - if they had "musical" dictionaries (what an idea!!! - I bet they exist in some form anyway!)
then this Lp would play under the entry Spiritual Jazz!
