Susanna Artzt in the "Gesellschaft für Musiktheater" on Saturday. -- The programme consisted of well-known pieces by Chopin and the Mozarts (Wolfgang Amadeus and Franz Xaver). Artzt's interpretation was intricate and passionate. -- There was some additional, unwanted, excitement in that the elderly gentleman to my right (in the first row) fell asleep as soon as the concert began, breathed heavily into my ear, and increasingly leaned in my direction. I was waiting for him to land in my lap.
