A Breton folk/rock band, Tri Yann was founded in 1971 by Jean-Louis Jossic, Jean Chocun and Jean-Paul Corbineau. Tri Yann (breton for the "three Jeans") started playing traditional breton music on traditional instruments like mandoloncello, dulcimer, psaltery, bombarde, cromorne and shawm. The band members are multi-instrumentalists, and usually the number of instruments on the stage is far greater than the number of musicians.

In 1976 with "La Découverte ou l'Ignorance" they started to introduce some rock elements like electric bass and drums. Today they are one of the longest-standing Breton music groups surviving from the folk rock revival of the 1970s. A popular live band in France, Tri Yann is famous for their outlandish costumes and theatrical presentation on stage.
