Biohazard frontman Billy Graziadei thrilled fans in Freiburg, Germany this week by getting a tattoo onstage during the band's performance of "Reborn," a track off the band's latest album.  Apparently, Graziadei noticed a tattoo parlor next to the venue the day of the shoiw and popped in and decided to have the work done.  Tattoo artist Tom Deyhle did'nt finish the piece before Graziadei had to leave for the show, so the singer asked him if he'd like to finish it onstage, and he accepted.  Check out a clip of the incident below.
