The band was formed by a group of Bretons and Scots musicians, members of The Silencers, Red Cardell and Ronan Le Bars Group with guests related to the world Celtic, inspired by their elders of the Buena Vista Social Club and the New Orleans Social Club which aims to popularise Celtic music by opening it to current music.

The music of The Celtic Social Club is a contemporary adaptation of traditional Celtic tunes performed by a group of seven musicians and guests chosen for their diverse backgrounds such as rock, folk, blues, reggae or hip hop.

The Celtic Social Club was formed in February 2012 when Manu Masko and Jean-Pierre Riou from the Breton band Red Cardell moved to New York City to mix an album with producer-mixer Ariel Borujow.
