He's alright, never been a huge fan of his but he seems to drift in and out of the music I listen to. He remastered the classic Exciter albums and just did a solo on the new Fozzy record for example.
I liked most of Alice in Hell and his early 2000s album with Time Bomb on it was decent.
Some friends of ours in Toronto cut a disc with him about 5 years ago. He's a pretty good producer and engineer.
