One of the four biggest bands in thrash metal has returned and is currently putting the finishing touches on their latest, forthcoming album.

After the band's last album, Worship Music, was quite a success, even going as far as earning a Grammy nomination, the band has been diligently putting the pieces together for a follow-up album that's even better.

In the sneak peek of the making of the new material, you'll see that the band is certainly proud of what they're making, so you should be ready for a good album when it drops in early 2016.
