sToa was founded in 1991 in Germany. Olaf Parusel (composition/arrangement) looked at this time for a new way to connect his musical and philosophical thoughts. He found a voice in Conny Levrow. In the same year the first song "Stoa" was released on the compilation "From Hypnotic ... to Hypersonic" (Hyperium). The album "Urthona" (Hyperium) followed in 1992, and sold ten thousand copies worldwide.
