In 1958 East Germany's Ministry of Culture decreed that at least 60 percent of the popular music and dance tunes played at events must originate in socialist countries. The amount of "foreign" or Western music in an entertainer's repertoire could not exceed 40 percent. This "60:40 rule" helped to promote the
development of homegrown pop and rock music in East Germany. Now Elias Arens, Moritz Grove, Barbara Heynen, Sven Kaiser, Ole Lagerpusch, Ingo Schröder, Bernd Stempel and Katrin Wichmann take pleasure in testing out this mix, performing both classic songs and little known musical jewels.
