This new release presents seldom performed but important chamber music works, alongside a Mozart standard. Their exceptional communicative power and their intoxicating atmosphere on stage are repeatedly praised by critics and have become the hallmark of ensemble 4.1. In addition to the masterpieces for this original setting by Wolfgang Amadeus Mozart and Ludwig van Beethoven, the ensemble is devoted to discovering rarely played compositions from the turn of the 19th to the 20th century. After many years composers like Walter Gieseking, Theodor Verhey, Heinrich von Herzogenberg and David Stephen are again being performed for an enthusiastic public.
