Beginning in 1935, Edmond Moreau was a very active performer and recording artist. He played the piano on more than 50 records for the Starr record company, having been part of numerous groups, such as:
- Trois Copains (with Henri Wattier on the violin and Arthur Pigeon on the accordion)
- Trois Citoyens (with A. Denault on the violin and G. Proulx on the harmonica)
- Trois Gaspésiens (with M. Gonzague playing the bones and Ernest Lussier on the accordion)
- Rigolos (with C. Deblois on the violin, Henri Taillon playing the bones and bombardon, Annette Richer singing, and Carmen Richer on the guitar)
- Trio connu (with R. Duplessis and R. Frereault)
- Trio Pigeon (with his son and Arthur Pigeon on the accordion formed in the early 1940s)
He probably also was a member of the Quatre Copains and the Trois Rigolos.
