I remember loaning Caravanserai to a fellow music nut (more of a 20th century classical guy w/some dabbling in jazz) and he loved it.
I wouldn't say I dislike it, but there's a lot of crap on there. (Lon/Jazzbo will disagree with us.) However, I disagree with you about the long tune near the end.
Yup.
In regards to Love Devotion & Surrender (the album, not the tune) mentioned upthread -- yes, something of a disappointment. I do like "Let Us Go Into the House of the Lord", they work up a nice groove and some of the guitar playing is ecstatic in a good way. WTF is up with the mixing of Larry Young on that album? He's barely audible.
