Well, Jimmy, you're being humble as usual. I would also think that having Garsed learn YOUR ad libs instead of the other way around shows how much respect those guys have for your creativity. I'm just a groove player, myself, but listening to your lyrical solo makes me want to give that stuff a try (only in private, of course...). Frankly, outside of just reflexively disgorging a torrent of (alas, random) notes, I wouldn't even begin to know how to construct a solo.
Several years ago I saw Planet X at SF Pound (Derek Sherinian, Tony McAlpine, Virgil Donati & Ric Fiberacci); a total gamma ray burst of mind blowing energy. But it wasn't numbing at all. I was standing right in front of Derek with a group of what turned out to be some of his buds from high school and had a blast checking out their interaction between songs.
I later attended a Virgil Donati clinic and talked to him briefly afterwards. As Jimmy points out, a totally cool guy.
