Serious fan of the Dan here...have caught them live a few times in the last decade. Tremendous songwriting talent with probably the best studio musicians in the world surrounding them. I also love each of the three Fagan solo albums (Becker solo is...not to my liking).
Forgive me if I've already mentioned him here...but a great chill out album for me is Joe Sample - Rainbow Seeker. Great musicianship on there as well. His work with the Crusaders is good stuff too...Street Life is a great album.
