Countess
One of the oldest still-existing Black Metal formations from The Netherlands is Countess, formed in 1992 by multi-instrumentalist / vocalist Zenon and synth-meister Vercingetorix. The both released a first demo (tape) in 1992, before they were joined by Orlok, shortly after he left the great band (and I do mean that, though apparently not many people share this opinion) Fallen Temple. In mean time, both founding members left, and Orlok is the driving force since.
