The choristers are often invited to take part in a multitude of engagements over the seasons: special events, accompaniment of artists on stage or for the recording of albums, TV shows and shootings, benefit events for foundations, festivals, concerts with symphony orchestras, musical theater, operas, etc. These engagements are made according to various participant formulas: mixed, boys or girls only, younger or older, in small or large groups, as needed. Les Petits Chanteurs de Laval can offer their public as well as producers, artists and symphonic orchestras a large group of choristers totaling more than 300 voices.
