Zwickau was B. Ardo's solo project back in the 1990's. The music of Zwickau is very different from that composed years later with Sangre Cavallum. The ritual ambient created under Zwickau is at the same time primitive and extremly deep. At least two cassetes were released through Ardo's personal label called Forgotten Blood. "Vincit Omnia Veritas" in 1994 and "The Serpent's Law" in 1995. A couple of songs also featured on some compilations. These releases are now golden itens for music collectors.
