The extraordinary Düben Collection contains over 2,000 manuscripts of 17^th- and early 18^th -century music by more than 300 European composers, collected by members of the Düben family and donated to Uppsala University in 1732. The collection is thought to include the music library of the Royal Swedish Court, where four of the Dübens served as Kapellmeisters from 1640 to 1726. La Modestine will perform a selection of rarely heard gems from the collection, including sonatas by Buxtehude, Becker and Reinicken.
