1951:
Founding of an accordion quintet (Rudolf Würthner, Karl Perenthaler, Lotte Aden, Waltraud Vogt, Max Neumann)
also in 1951:
Founding of a Chromonica trio (Rolf Glass, Walter Stephan, Siegfried Sugg). Siegfried Sugg left the trio in 1954. His successor on bass was Heinz Herre.
Both ensembles served to expand and enrich the orchestra’s programme, but also performed independently.
And a lovely ladies‘ quartet:
Edith Gelück, Lore Winter, Waltraud Vogt and Lotte Aden
