What a great thread! As a child of the late 60's/early 70's I'll throw a few of my favorites out that are still on my turntable weekly:
Nitty Gritty Dirt Band - Dirt Silver and Gold
New Riders of the Purple Sage - NRPS
Roxy Music - Avalon
Allman Brothers Band - Fillmore East
The Who - Who's Next
Santana - Abraxis
Pink Floyd - Umma Gumma
Marshall Tucker Band - A New Life
Crosby, Stills and Nash - CSN (just bought 180g reissue from Acoustic Sounds)
The list could go on and on, but I'll leave space for other people...
