Undulant was formed in '90 by four childhood friends, Kasper Pilemand (vocals, guitar), Kasper Steensen (drums), Kasper Andersen (bass) and Pitter Bacher (guitar). They released two demo casettes ("demo '92" and "Know I'll Never") and the CD "Drape". During the six years the band existed shows were played in Copenhagen and Hillerød mainly. The latter was the band's home ground where they played both as headliners and support for Konkhra and Dominus, among others. Inspiration came from bands like Machine Head and Invocator.
