Blou began in the autumn of 1994 in the Canadian province of Nova Scotia when Patrice Boulianne, met Len LeBlanc and Daniel LeBlanc.
Later the trio became a sextet when Paul Melanson, Owen Muise and Briand Melanson joined. In 1998, Blou self-produced its first recording, "Acadico". "Acadico" was the first CD by an Acadian group that had a European distribution.
In 2000, Blou changed its lineup. Their second album, "Rhythm 'N Blou" had a more up-beat sound than "Acadico" and the band toured internationally. In 2003, Blou released their third album to celebrate their upcoming tenth anniversary. Also that year the band won the Prix ZOF-PassepArt-TV5 award. On October 17, 2005, Blou released the first single, "Come Away Café" from their unreleased fourth album, "Pied-à-terre." "Pied-à-terre" was later released on February 14, 2006. With this new CD Blou became a solo act as front-man Patrice Boulianne has taken the name as his own.
