1755 combined folk, country and rock, with traditional folk song lyrics, or original compositions from the band members or from Acadian poet Gérald Leblanc. The most of the songs are performed in the Frenchdialect of south eastern New-Brunswick, known as "chiac", but some compositions are in English as well. The group is considered an icon of modern Acadian culture, and is credited for launching the modern Acadian musical scene at the international level and for influencing several Acadian artists and bands that came after them, such as Fayo or Dominique Dupuis.
Although officially broken up, 1755 often reunite to perform shows and summer tours, especially during Acadian-related festivities such as National Acadian Day. A particularly notable show was at the Moncton Coliseum, during the first Acadian World Congress in 1994, which was filmed and turned into a live album Les retrouvailles de la famille and a video release on VHS and DVD.
