Charles Rondelet

He was a house tenor in Liège in the late 1920s, and closely connected to that city; he was also one of the first classical singers to record songs in Walloon dialect (which is so incomprehensible that other French speakers need a translation). But Rondelet also sang in France (he was a member of the intertwined opera theaters of Arras, Cambrai, Denain, Saint-Amand, Caen, Lisieux and Bayeux at least in the 1923/24 season, but probably already before that). In January 1932, he participated in a radio concert in Montréal, featuring only music related to Liège; he won't have traveled all the way to Canada for that concert only, and I suppose his visit will have had to do with Montréal's considerable Walloon community.

I wish to thank Anton Bieber for the recording and label scan.
