As early as 1981, Chrislo Haas created the pre-techno classic "Los Ninos Del Parque" in collaboration with Beate Bartel from the band Mania D. and singer Krishna Goineau, under the project name Liaisons Dangereuses, whose spartan, hard beats influenced an entire generation of techno producers. In the late 1980s, he performed with the Crime And The City Solution formation, among others, and released several albums for Tresor in the 1990s.
