Pyogenesis is alternative rock band from Hamburg, Germany. Formed as Immortal Hate by Tim Eiermann, Joe Proell and Pit Muley, they recorded their demo Pyogenesis of a Festered Corpse in September 1990. With addition of second guitarist/vocalist Flo Schwarz, they renamed to Pyogenesis. First EP, Ignis Creatio, was released in 1992 on Osmose. Stylistically it was a death metal with heavy gothic/doom influences. Pete was then replaced by Wolle Maier. Second EP, Waves of Erotasia and first full album Sweet X-Rated Nothings, released in 1994 on Nuclear Blast, was more into gothic metal genre, having its own style, differentiating Pyogenesis from other bands of the same genre. Joe Proell left the band and was replaced by Roman Schönsee. Next album, Twinaleblood, was characterized by strong addition of pop punk and alternative rock influences, which finally result on their 1997 CD Unpop, when band finally departed from metal altogether. Tim Eiermann and Wolle Maier then left Pyogenesis. There are definite German techno music influences in the mid-90s music of Pyogenesis, and its inclusion in the underground music scene was demonstrated by the inclusion of their song "Love Nation Sugarhead" on the CD along with the April 1997 issue of CMJ New Music Monthly magazine. Pyogenesis's musical style includes elements from atmospheric, gothic rock, death/doom metal, alternative, punk, and techno Members Flo v.
