Billy tells WMSC 90.3: "Right now, I think The Brotherhood Of The Snake is what we're going to title the album, and it's the first single. I think it's probably going to be a freebie that we'll just give people to check out."

He also hints he's been inspired by his Catholic heritage, ancient cults and the "connection between religion and aliens" when writing the follow-up to Dark Roots Of Earth.

He says: "The main part in The Brotherhood Of The Snake is basically, 5000 year ago, secret society stuff. We're really fascinated. I was born Catholic and seeing all these shows on the connection between religion and aliens, it makes you think about everything. There's a fascination with that.
