I hadn't really listened to them since High School but I found one of their CDs in the CD wallet in my car last night and forgot how much I used to dig these guys. I know there are some other fans here. Ralf Scheepers definitely is a better vocalist than Ripper and should have got the gig. (And I like Ripper) Love the Gamma Ray albums he's on as well.
The first two are great, after that they get hit or miss. They are always great live, though.
