Freddy Burger already made a name for himself in the local scene before the age of twenty as manager of the pop group Les Sauterelles and as organizer of pop concerts and dance events. With the management of Pepe Lienhard and numerous other Swiss artists, the foundation of the agency Rent-a-Show AG as well as his own nightclubs, the young businessman already achieved national fame at the end of the 1960s. The former co-owner of the concert agency Good News, together with his partners André Béchir and Peter Zumsteg, had a lasting impact on the Swiss concert scene. With the musical Tell, he took the plunge to produce early on in his career. With the exclusive management of Udo Jürgens, he finally made his way into international showbiz in 1977. In a phase of diversification, the former ice hockey player and Swiss general importer of PUMA managed to create synergies between sport and show business. In addition to Udo Jürgens, Freddy Burger entered into further cooperations with various stars. For example with Nana Mouskouri, for whom he coordinated worldwide concert appearances for decades.
