The aim of Association pour le rayonnement des orgues Aristide Cavaillé-Coll de l’église Saint-Sulpice, à Paris (AROSS) is to promote the Saint-Sulpice organs through concerts, masterclasses, publications and education initiatives for schoolchildren.

AROSS organizes one concert per month from March to June and from September to November. The concerts range from choir and organ concerts, soloist instrument performances (such as cello, horn, trumpet and so on) and organ recitals. Musicians are featured live on a large screen in the nave and broadcast online – AROSS is the only French organ association broadcasting its concerts live on the Internet.

Donors to Friends of Fondation de France help AROSS continue to organize these concerts.
