The musical life in the late 18th century's Russian metropolises still needs to be researched more extensively: With this recording, the musicians of the Altera Pars ensemble impressively demonstrate what masterpieces are waiting for their discovery. The international ensemble "Altera Pars" (in English: Other Side) specializes in the performance of baroque and classical music. The musicians are leading soloists of European orchestras on period instruments. This allows for a variation of the line-up from 3 to 9 people and opens up a rich chamber repertoire from the 18th to the early 19th century. In the last four years, the ensemble initiated a much-praised series of concerts in the Oldenburg Palace.
