The young musician Ralph Osterwalder, born in Bern in 1922, is tired of working in a big band. He dreams of a small, flexible ensemble. In 1944, he founded his own combo in a hotel room. In 1949, fierce disputes arose. The newly founded Hazy Osterwald Sextet, featuring Sunny Lang, Dennis Armitage, Curti Prina, Werner Dies, and Johnny Ward, soon made international music history. Fast-paced, catchy music, interspersed with humorous show interludes, became the band's unmistakable trademark.
