Mystery time! Formerly known as Undead, five-piece Undead Prophecies do the OSDM thing with aplomb, conjuring masters like Morbid Angel, Obituary, Death and Celtic Frost. Nobody knows all that much about the personnel, yet they're touted as a supergroup. They really dig on Evil Chuck, yet still manage to evoke their own voice on debut album False Prophecies (Listenable). Intrigued? Check out the album teaser below.
