The latter featured Bruno Barre (violin), Youenn Le Berre (flute), Jean-Marie Renard (guitar), Roger Schaub (bass), Ricky Caust (guitar) and Arnaud Rogers (drums). For Gwendal 4 they merged Celtic tunes with rock, jazz and reggae. In 1982, constant changes in personnel resulted in the recruitment Robert Le Gall (fiddle/guitar). He and Le Berre then became the core of the group, with both writing and deciding on the musical direction. The band’s 90s set Glen River proved to be a pleasing, swinging collection with the overtones of a pure folk jig.
