From 1951 to 1963, Toni Stöckli was the first to hold the position of manager of the Klubhaus Konzerte. It is thanks to him that the series welcomed its first prestigious guests, such as Herbert von Karajan, Karl Böhm, Sergiu Celibidache, Maria Callas, Yehudi Menuhin and Jascha Heifetz. The Swiss orchestras partly looked upon these famous artists from abroad as a threat, an attitude which even led to a few harassing moments with the migration authorities. In October 1953, the Vienna Symphony Orchestra led by Karajan was for instance not allowed to perform in Berne. Stöckli quickly relocated the concert in Fribourg, bringing the audience to the concert venue with a special train service. The situation was defused when the Klubhaus Konzerte decided to also take Swiss ensembles such as the Tonhalle Orchestra or the Orchestre de la Suisse romande on tour in the country’s different linguistic regions. The highlight of the 10th anniversary of Klubhaus Konzerte, in 1958, was the Swiss premiere of Stravinsky’s "Threni: id est Lamentationes Jeremiae Prophetae", which the composer conducted himself.
