Ex-Anthrax vocalist John Bush got up on stage with Metal Allegiance during their September 25 show to perform a handful of Bush-thrax classics. Bush performed "Only" and "Room For One More" off the 1993 album Sound Of White Noise, as well as "What Doesn't Die" off the 2003 album We've Come For You All. If you've ever seen any footage of Bush ever, then it should come as no surprise that he absolutely killed it.
Bush sang for Anthrax between 1992 and 2005, and then again between 2009 and 2010.
