Nemtheanga has 1 Insidious Disease concert.

Insidious Disease was formed in late 2004 by Silenoz (Dimmu Borgir) and Jardar (Old Man's Child) with drummer extraordinaire Tony Laureano (Angelcorpse, Nile). Later Shane Embury (Napalm Death, Brujeria, Lock Up) joined the fold to complete the pounding pulse and rhythm section. The search for a fitting vocalist was not easy since the band wanted to have a distinct main voice that differed quite a bit from the typical, interchangeable low guttural gurgling.
