Listen to Anthrax on iHeartRadio

The guys in Anthrax are making noise again. 

Guitarist Scott Ian recently took to Twitter to let fans know that he and his bandmates have started working on the follow-up to 2011's Worship Music.  

He says the new tunes are coming "fast and loud," joking that anyone within five miles of his house can probably hear it all. 

Ian also posted a picture of the metal vets jamming in his house with producer Jay Ruston. 

Ruston previously worked with Anthrax on Worship Music and the covers EP Anthems, which came out back in March.
