Desjardins and his friends formed the country rock ensemble Abbitibbi in the 1970s; Desjardins played piano, guitar, and sang. When the group disbanded in 1982, Desjardins pursued a solo career. He released a number of solo albums, including Tu m'aimes-tu in 1990[2] and Boom Boom,[3] which appeared on the RPM 100 Top Albums list in 1998.[4]
Desjardins also found work scoring films, especially documentaries. This involvement in the Quebec film industry even led him to co-direct a number of feature-length documentaries. He was known for his environmental activism, especially with regards to protecting forests from over-exploitation, and to promote this he and Robert Monderie created the documentary film Forest Alert (L'erreur boréale) in 1999.[5] In 2007 Desjardins, again with Monderie, created The Invisible Nation (Le Peuple invisible), a documentary about the Algonquin nation in Quebec.[6]
Desjardins went on tour in 2013, promoting his album L'existoire; after that he made occasional live appearances, including the 2018 Festival guitares du monde in Abitibi.[7]
In 2017 a group of singers came together at Steve Jolin's Rouyn-Noranda record company to record Chanter Richard Desjardins, a tribute album of Desjardins' songs.[8][9]
He was profiled in Lisette Marcotte's 2019 documentary film The Last Nataq (Le dernier Nataq).[10]
