Hardly any other event during Mozart Week has remained so vividly in visitors' memories as the 1994 production of Ombra felice.

Mozart's creative excess in the field of opera is evident not only in fragments of stage works such as Zaide KV 344, L'oca del Cairo KV 422 and Lo sposo deluso KV 430, but also in the more than seventy arias and ensembles he composed as individual works. Some of these are abandoned or unfinished drafts, as Mozart's singers (or sometimes Mozart himself) were not entirely satisfied with them, while others were contributions to foreign opera productions, which were often performed in the form of pasticcios at that time. This broad compilation thus provides a good overview of Mozart's aria compositions.
