I saw him live twice with Deep Purple and during the last G3 tour and I must say I was really impressed with his ability. I find his style of playing very interesting as I think he can mix a couple of styles and come out iwth simething quite interesting. I have yet to listen to his solo band but the Dregs, Kansas, Deep Purple and Flying Colors are all great and his work in those bands is very very good
That has always been his (most recognizable and praised) trademark. Steve has always been an extremely versatile player who built his style upon a number of different (and oftentimes disparate) musical influences. Plus, he has always been a great composer too (which always set him apart from the guitar virtuoso crowd to me).
I too saw him twice last year. Once with the SMB and another time with Flying Colors. Both shows were great and had me giggling like a little, wide-eyed schoolboy.
If you've never checked the Steve Morse Band (or his actual solo records), you owe it to yourself to listen to "High Tension Wires" as soon as possible. That's Steve Morse at his purest. And the songs themselves are just wonderfully written (and, of course, performed).
