The four galleries of the Abbey Church of Muri offer optimal conditions for multi-choral music, as at St Mark's Venice where the music of Gabrieli flourished. So as to include the historical organs of the church, two cornets have been produced whose pitch exactly matches that of the Bossard organs of the Abbey Church of Muri.This recording is the first sound documentation of this essential musical practice at the Abbey Church, comprising of works dating from the '20s and '30s of the seicento, characterised by exuberant virtuosity and joy of playing by Les Cornets Noirs, founded by Gebhard David and Bork-Frithjof Smith in 1997.
