The list is getting a little unwieldy, and it probably should be broken up--either according to decade, or maybe genre. Something. I'll look at it after the list is complete.
So, here's some more...
Marshall Tucker Band - Self-titled album, Searching for a Rainbow, or Carolina Dreams
The Doors - Self-titled album, L.A. Woman
Grateful Dead - Workingman's Dead, American Beauty
Simon and Garfunkel - Bridge Over Troubled Water
Neil Young - Everybody Knows This is Nowhere, Harvest
The Band - Music From Big Pink, Self-titled album
Leonard Cohen - Songs of Leonard Cohen
Byrds - Sweetheart of the Rodeo
Crosby, Stills, & Nash - Self-titled album
Traffic - John Barleycorn Must Die
James Taylor - Sweet Baby James
Carole King - Tapestry
Stevie Ray Vaughan - Texas Flood
Blind Faith - Self-titled album
[Add Elton John's first 2 albums]
Okay, that's enough for now. Some more will pop into my head, and maybe I'll look through my albums for some other ideas, but that's most of them.
