Megadeth frontman Dave Mustaine has made a career out of breakneck-speed thrash metal, but his between-song chatter hogged the spotlight lately. I learned a valuable lesson, he told Rolling Stone recently, after comments he made at a Singapore concert caused an uproar. (Mustaine made it sound like he believed President Obama was behind the mass shooting at the movie theater in Aurora, Colo.) Consequently, fans should expect less controversial crowd banter and more by-the-books mosh fodder when the veteran band headlines Boises Knitting Factory.
