Another great is a Phil Keaggy protoge' of sorts; Ty Tabor from King's X. He's one of the most unique rock guitarists I've ever heard. Tone from Heaven.
You're not kidding. Ty is awesome. I saw King's X here in Nashville a few years back with Galactic Cowboys. What a great show. Ty's tone is killer. It's hard to believe he gets that kind of tone from a solid state amp. He was using a Zion that night mostly.
The thing that was so amazing was how much sound three guys could make and you really didn't miss anything. It was very full and big. Honestly it sounded like a CD. And they were so tight both musically and vocally. They did a breakdown during Groove Machine that would drive ordinary musicians nuts. It was full of odd time signatures and rests that were impossibly complicated but they nailed them. Just a great band.
The Galactic Cowboys were incredible too.
Funny story. During King X's set Doug's bass rig went down and they had to borrow a rig from the Cowboys who had already put their stuff up. While they were setting up Ty jokingly asked for requests. True to form whenever someone in the south asks for requests in such a fashion someone is going to yell out - "Free Bird!" And of course they did. So Ty broke into it for a few bars. There was something I never thought I'd see-King's X doing southern rock.
On the subject of Phil Keaggy. As incredible as he is with his usual acoustic-oriented stuff, have you ever heard him rip? There's a song on the first 2nd Chapter of Acts album called "Yahweh" and his playing is just unworldly good on it. It's kind of heavy to be 2COA. He also played guitar on a Matthew Ward solo that was released in the late 70's and done some incredible things there too working solely as a "band" member. And what a band it was. Phil Keaggy on guitar, Ray Parker Jr on guitar as well, Abraham Laboriel on bass, Keith Green on piano, and Michael O'Martian on synth. I'm not sure who the drummer was though. The album was Matthew Ward's first solo record and was entitled "Toward Eternity". It's out of print now but you can hear some excerpts at the following URL
