I doubt anyone on here has ever heard of them, but they put out some classic American metal and got big in Europe. A lot of their stuff is on YouTube, including some shows I attended back in the 80s.
Unfortunately they are not with their original singer who was on their first two albums and they're playing without one original guitarist (who is a Grammy winner) for this gig, but it should still be a good one.
If you're in the Stamford area, come down and check them out next Tuesday. It should be a killer show in a small bar.
O-Bass, their third album cover alone ought to lure you in.
