Musica Transalpina is proud to present the first known American performance of Emperor Leopold's Missa pro defunctis, which he composed for the death of the Empress Margaret Theresa in 1673.  The marriage between the Infanta Margaret Theresa and Holy Roman Emperor Leopold I. was one of the most important dynastic alliances in history, so her untimely death was of immense historical significance.  We are recreating the music that accompanied this historic event, and now you get to hear it.
