Make sure you listen to (in no particular order):
-- Brian Wilson, "That Lucky Old Sun"
-- Felix Cavaliere and Steve Cropper, "Nudge It Up A Notch"
-- Oasis, "Dig Out Your Soul"
-- Rodney Crowell, "Sex and Gasoline".
If you get a chance, read Robert Stone's wonderful appreciation of Dr. Albert Hofmann. This man inspired a lot of great music. God bless him.
