I went to Reverend Horton Heat last night and they were awesome. I've seen them before a few years ago. Every member in the band is so great you could just focus on one of them the entire show. Anyways, before they played, there was this S&M show (as best as I can describe it) of these guys insanely tattooed and peirced in ways I didn't know existed. They even had balls implanted under their skin, and horns even. One of them was a topless girl who had nothing but tiny peices of electrical tape to cover her nipples barely... otherwise she would be exposing herself, wouldn't she? Well they peirced some hooks into her sides and suspended her until she was bleeding a bunch. They did that with all the guys, each time hooking them from a different place, and would swing them across the stage. They were hooked to a cross at one point even. Needless to say they were all pretty bloody by the end of the night... I have to admit, it was pretty fun to watch! Here is a picture of the same type of stuff.
