Atma and also Deen Castronovo were absolutely incredible, I'd also be interested to know what they're up to...
I think both have been keeping quite busy: Deen's been in all sorts of more or less metal related bands and is in Journey now, as far as I know (and should be coming around here soon with them), actually doing vocals on some stuff as well. Not my cup o'tea, but he seems to be doing well.
Atma is a bit harder to track, but I know he's been involved with Kotzen and Howe, and has recently been associated with the EssenEss Project (I think that's how it's spelled), with the likes of Steve Smyth. Worth checking out, I think.
