I, too, will participate in said straight up murdering, but only in regard to that strange man who constantly screams "BLACK ROSE IMMORTAL!" He has attended every Opeth show I have been to, and I harbor a deep hatred for that man, namely because of the nerve he has to request something so foolish of the great Akerfeldt.
At the last NYC show, some guy kept yelling Black Rose Immortal. Mike then played a little portion of it on his guitar and said "that... fuckin' masterpiece."
