Liliental was a German studio band formed by Dieter Moebius of Cluster. The group included notable musicians such as Hellmut Hattler and Johannes Pappert from Kraan, along with Asmus Tietchens and Okko Bekker. Conny Plank produced the album Liliental, which was recorded in 1976 but released two years later on Brain Records. The album featured the standout track "Wattwurm". The project was a one-off supergroup effort, with all members returning to their individual projects after its completion.
