There is more than one artist with this name: 1) The multi instrumentalist Peter Frohmader is the founder and leader of Nekropolis (heavy, primitive & dark electronic rock group launched in the late 70’s).
Three major albums have been published under the name (Nekropolis, Nekropolis 2 & "Le culte des goules" in 1985). More in the vein of krautrock dark experimentations (with tape manipulations and doom bass sequences), "musik aus dem schattenreich Nekropolis" was released under the same name (1978-79).
