Yesspaz-
The three GH studio albums are OOP and hard to find, but they are often listed on ebay.
For a 2-CD reunion concert, go to Phil's site:
www.philkeaggy.com
If you REALLY want to hear Phil's best licks, find the 2-CD live set by The 2nd Chapter of Acts, Phil Keaggy, and "a band called david" entitled "How The West Was One". There is one track where Phil plays a 5 minute unaccompanied electric guitar solo that is like a "mini-concerto". It's amazing!
I have most of Phil's albums. Seen him live about nine times. He is truly the Victor Borge of the guitar.
