Try From the Beginning by Emerson Lake Palmer. Its more complicated than it looks. You can pull partial tabs/chords for it off of this site. I have it tabbed completely, if you want it, but I won't post it publicly, I will just send it to you directly. Take a listen to it first on playlist or youtube or somewhere.

Acoustic. Try anything Dylan. Pierce Pettis and Bruce Cockburn are excellent.
