The Suter concerto apparently with these performers (same concert, too?) will be on a digital release (https://www.prestomusic.com/classical/products/9555975--suter-violin-concerto-in-a-major-op-23-live) listed by Presto as due out 12 January 2024.
Is "Swiss Orchestra" a specific orchestra or a placeholder description ("a" Swiss Orchestra)? It's also the name on the Prospero Classics digital recording, so I'm assuming the former...
You were right to assume the former, it is a specific orchestra (https://swissorchestra.ch).
