They played melancholic synth music with ethereal female vocals, and can be considered one of the first heavenly voices bands. In fact, they participated on the first volume of the “Heavenly Voices” series by Hyperium.
Their debut album, titled “Gods Tears”, was released in 1993. In the same year they started to record a second album, supposedly titled “Gods Laughter”, but it was never finished.
