Yeah i agree schenk, to me satch has always had a really verse-chorus-verse-chorus structure that does become very predictable after a while, that being said, songs like summer song, back to shalla bal etc. are still great regardless of how symplistic the structures are. I also recon satch has only about 5 tones that he choses from when writing....
Another great guitar album that i dont think has been mentioned : SRV - texas flood
