The anonymous violin concertos in Trondheim

Trondheim, June 4th 2017: No less than nine anonymous 18th century violin concertos are preserved in the NTNU’s manuscript collection in Trondheim. The identities of the composers is a mystery that remains to be solved. All we know is that this music was performed in Trondheim throughout the 18th century, by professional musicians, for a wealthy audience with a taste for the latest continental art.
Last week, I gathered a few of my dear colleagues in the Trondheim Symphony Orchestra for a read-through after rehearsal. This is what we recorded. Most likely, this is the first time this music has been played since the 18th century.
We would like to ask you, dear listener, what you think: Can the composer be identified? If you have any clue, opinion or knowledge to share, please get in touch.
