Heavy metal teen trio, BABYMETAL, has just been added to the lineup for Heavy Montreal! Heavy Montreal is a three day heavy metal festival boasting appearances by big names such as Slayer, Anthrax, Lamb of God and many more. If I was these girls' mom, I'd be...terrified, frankly. The festival takes place August 8-10 and weekend tickets are on sale now, so get 'em while they're hot!
