Microtonal metal hasn’t got much light shed on it.
Obscurer than any obscure band, microtonality has somehow existed since the XVIth century, and probably before that.
Metallicpuppetmaster, with a 24EDO BC Rich (a standard guitar is in 12EDO, so instead of semi-tones, this guitar has quarter-tones), a drum and some silly lyrics, succeeds in bringing some focus on this uncommon musicality.
This song is brutal, and the guy is certainly versatile. Guitar, drums, and singing! Wow! That guy could record an album all by himself and it would sound absolutely killer!
