Nice posts so far! Another couple additions:

Joni Mitchell "Hiejra" - Wow! What a great album. Amazing lyrics (as usual) and stellar guitar work by Larry Carlton I believe.

Van Morrison "Common One" - I can't believe I overlooked this one. After years of hearing how bad this record is, my dad recently bought it. Amazing, albeit over the heads (perhaps) of a lot of more casual listeners. Lots of "meditative Van."

Skip James Biograph reissue - Doesn'e get any better than this guy. haunting, soulful readings of some of his songs. These Biograph reissues are pretty good. Too young to remember the originals, but and loving the other 2 I have - Son House & McTell.
