A timeless sound (think Hüsker Dü, Leatherface, and what I think early Face to Face sounds like until I listen to it again), a gruff, noisy melodic pop/punk.
Non-purist rockabilly (veering toward punk more than American roots music). Paces cross over into psychobilly, but also sweet melodies and trembling passion.
Mod music played by guys more interested in writing good music than teasing their hair to look like they just woke up. Ex-members of Garden Variety & Milhouse.
Ihsahn and Samoth began Thou Shalt Suffer before Emperor. Some scary/beautiful moments of traditional classical, but it’s really just a guy experimenting.
