Anthrax was one of the very many bands to have performed at Knotfest over the weekend, and along with that performance came a little bit of new music! Before the group launched into "I Am the Law," they jammed on what sounds like an awesomely heavy new song.
The group hasn't said what the plans are for the new record, but it will be the first effort from Anthrax with former Shadows Fall guitarist Jonathan Donias shredding it up on lead guitar.
