I had never heard of him before, but I googled him and he sounds good. Are all his (or is it 'their') songs guitar instrumentals? I'm a big fan of that if so....yngwie, Vinnie Moore, etc.
I know those guys are not all instrumentals, but a lot of their best material is.
Guthrie has played on some vocal albums (can't remember which right now), but they really do nothing for me. It is his Erotic Cakes CD that is the best instrumental guitar album of his. His work with the Aristocrats (two cds) is great playing, but more "jammy" than songs in my view.
By the way, Vinnie is just so good. Love all his solo stuff. They only Yngwie album I liked was the first one.
