Christof Glowalla recorded and self-released a 2-track 7″ single in 1980. The A-side ‚Erde 80‘ became a clubhit and therefore the single a rare and sought-after item. He had a few more songs and one of them has been released on a split single with Bakterielle Infektion on genetic music in 2001. A 10″ with 5 tracks incl. the original single and the track on genetic came out on Medical Records in 2012.
