I had not heard of 17th century baroque composer Nikolay Diletsky until now. According to Wikipedia, he was, ” …a music theorist and composer born in the Kyiv Voivodeship of the Polish-Lithuanian Commonwealth and active in Russia.” Today’s Beautiful Music is Nikolay Diletsky’s sacred word, PRAISE THE NAME OF THE LORD, sung by American Baroque Singers. You can also read more about the composer using the link below.
