It's not only amazing that this composer is virtually unknown, given the extraordinary quality of those concerti. It's even more amazing that, after the publication of this CD, the composer still remains unknown and this is the only CD with his music!
For me this is one of the most beautiful baroque (or rather preclassical) CDs I've ever listened to. Behind the established structures of baroque and preclassical music, those concerti are rather original with surprising turns and dissonances sometimes. Umstatt's concerti got elegance, beauty, virtuosity, but also captivating expressiveness. They are accomplished masterworks of the highest order, IMO.
