Supermax

Supermax is a project of the Austrian musician and producer Kurt Hauenstein, best known for "Love Machine", a 1979 German number four single that peaked at #6 in Switzerland, #9 in Austria and #96 in U.S. The members of the band were Hauenstein, Hans Ochs (g), Ken Taylor (bg), Lothar Krell (Keyboard), Peter Koch (dr) and the singers Cee Cee Cobb and Jean Graham. In 1981 Supermax toured as the first mixed-race band through South-Africa and Venda. 21 concerts were played by the band.

Despite warnings and death threats, Supermax finished the tour, but this made some countries refuse permits for entry and consequently the group was black-listed by some political organizations.
