Harmonium was one of the most influential bands from Quebec. Lead vocalist and guitarist Serge Fiori met Michel Normandeau (vocals and guitar) in a theatre music meeting. Later on in 1973 they met bassist Louis Valois and became Harmonium. In November of 1973 the group performed their first air play on CHOM FM. They played 3 tracks: "Pour Un Instant", "Un Musicien Parmi Tant D'autres", and "Un Refrain Parmi Tant D'autres". The first 2 songs were demos at the time and were later recorded professionally to be put on their first album, Harmonium.
