Nightwish

A very talented, original, and powerful band. Takes great parts of metal, classical, and opera and fuses them into beautiful music.

Nightwish rocks the house.

NightDarker 

The nemesis and polar opposite of spaceman, and a known gatorade fiend. Writes in barely comprehensible ebonics.

May in fact be spaceman himself, or merely a clone gone bad.

Spaceman
Fighter of the NightDarker man
Champion of the sun
You’re a master of weird posts and snowmen…for everyone
