My HS randomly had a large and random collection of people that wore Pro-Pain shirts, spanning all social circles. Not only did they not have any hits, they weren't even all that big by heavy metal standards; just one of many discount Pantera knock offs that were around at the time. My theory is that they must have opened for Pantera, who would have drawn more than just the usual concert goers, so it would have been the "first show" for many of them.
