Megadeth's fifteenth studio album includes Adler as a guest player following Shawn Drover's departure last fall, and former Angra guitarist Kiko Loureiro as a new band member in place of Chris Broderick.

Megadeth recently launched a PledgeMusic campaign to provide the opportunity to bring fans into the recording process with a list of incentive packages.

"Pre-order the album digitally, on CD or on vinyl plus tons of other unique offerings like signed CDs, signed vinyl, gear from the studio and much more," says the group. "No matter what you order, you will get access to a variety of behind-the-scenes content such as photos and videos from the writing and recording sessions. You'll get full access to the process in real time."
