The "chief machinery operator" for German industrial terrorists Einstürzende Neubauten from the band's inception in 1983, F.M. Einheit has had plenty of time to record side projects between his group's usually relaxed release schedule (one which also permits bandmate Blixa Bargeld to play with Nick Cave's Bad Seeds). Einheit recorded his first, 1990's Stein, just after the sessions for Einstürzende Neubauten's Haus der Luege. Then he formed a band -- confusingly named Stein -- with Ulrike Haage and Katharina Franck of the Rainbirds; the project released Steinzeit in 1992 and Königzucker two years later; in the meantime, he released his second proper solo album, Prometheus/Lear, in 1993. With poet Andreas Ammer, Einheit recorded the Radio Inferno LP (which also included the talents of DJ John Peel and guitarist Caspar Brötzmann) and recorded again with Brötzmann on the album Merry Christmas in 1995. Einheit returned in 1997 with Sensation Death for Invisible Records.
