The singer in this band just totally destroys, he has amazing power metal cleans with brutal death metal growls.
They just came out with their EP, and its available to stream on their band camp:
Nostalgia | Corelia
Have been really digging these guys, also FYI the singer is currently on tour with The Human Abstract (since their singer left).
The cleans dont sound very power metal to me at all? It just sounds like most other vocalists in this genre, but he has a much larger range. If anything, the vocalist sounds to me more like Periphery meets Myles Kennedy.
