The Age Of Metal recently conducted an interview with vocalist Chuck Billy of san Francisco Bay Area metallers TESTAMENT. You can now watch the chat below.

Speaking about the progress of the songwriting sessions for TESTAMENT's follow-up to 2012's "Dark Roots Of Earth", Chuck said: "We have five or six songs demoed up. There's still probably a lot of tweaking on it, I'm sure. But, hopefully, within the next couple of months, being on the road, we can get some time to just kind of mess with some stuff."

Asked if the new TESTAMENT songs will have one unifying lyrical theme, Chuck said: "We haven't really thought about it. I don't think there's been a concept on this yet. We're just kind of writing songs. We're just getting as much songs of me and Eric [Peterson, guitar] working together, demoing. So it's advanced, but it's early, at least with the rest of the guys. 'Cause me and Eric are doing all the writing and demoing."

Regarding a possible release date for TESTAMENT's next studio CD, Chuck said :"I don't know. I can't set a date. But at this point in time in our careers, when it's ready, it's ready. And at the end of the day, we're the ones that have to live with it for the rest of our life and tour on it. So we wanna make sure it's ready. And we're fortunate to have Nuclear Blast really supporting us and not sweating us on it. They're just, like, 'When it's ready, we'll know, we'll be ready and we'll go.' So I hope towards the end of the year, it's done and finished."
