Nemtheanga has 3 Cryptopsy concerts.

Originating from the Montreal area, this group first appeared in 1992, when it was called Necrosis; in the same year it was reincarnated under the name of Cryptopsy. With just a demo called Ungentle Exhumation and then the album Blasphemy Made Flesh (1994), the group acquired a solid reputation on the international scene. Their release of None So Vile in 1996 was the first burst of brilliance in their career. From that point the group clearly outclassed other groups by reinventing the style, today categorized as extreme music.
