Ar Re Yaouank (The young people) is a Breton music group, established in 1986 by two brothers born in Quimper, Brittany, in northwestern France, Fred and Jean-Charles Guichen (16 and 14 years at that time) playing the diatonic accordion and the acoustic guitar respectively. They were joined in 1987 by Gaël Nicol (bombard and bagpipes), David Pasquet (bombards), then in 1990 by Stéphane De Vito playing the electric bass.
With the energy of the rock, while respecting the spirit of the traditional tunes, they add a very fast rhythm, bringing dancers in the trance. Thus, they revitalized the Fest Noz (night festival), attracting the young audience and new followers. The group disbanded in 1998, and each continued to evolve in the Breton music, with various bands. The Brothers Guichen mainly worked as a duo under their own name.
