Tonight’s mystery artist’s on one of their tours routinely fired an actual machine gun from the stage. Know who?

I found this dangerous piece on information on Ultimate Guitar told by Judas Priest lead singer Rob Halford.  Rob says he’d shoot it off after the song ‘Genocide’. He also assures us that it was not only full of blanks but as an extra precaution a fire marshal watched them load it before every show.

Here's the band with tonight's featured song.
