Not For Flying Colors I thought was "meh." The Island of Lost Keyboards I thought was really good, I like it quite a bit better than the actual Flying Colors album. The Whirlwind demos is one of my favorite inner circle releases.
My favorites, off the top of my head: Whirlwind demos, samples of Jesus Christ: The Exorcist, Flevo Festival DVD, making of One DVD pt 1 and pt 2, Neal Morse in the 80's and 90's, and From the Cutting Room Floor. The first two on this list are the top two, the rest are in no particular order. I tend to like the cd's better than the dvds. Just don't have time to watch the dvd's but can listen to the cds while I work.
Neal tweeted that the next release will be Neal Morse in the 90's. Can't wait for this one, as I liked the last one that was doing something similar.
