Shaped in Brittany, France, in 1973, this folk group documented acoustic albums of Celtic material before Gwendal 3, and subsequently turned for an ‘electric’ lineup. The last mentioned highlighted Bruno Barre (violin), Youenn Le Berre (flute), Jean-Marie Renard (electric guitar), Roger Schaub (bass), Ricky Caust (electric guitar) and Arnaud Rogers (drums). For Gwendal 4 they merged Celtic music with rock and roll, jazz and reggae. In 1982, continuous changes in employees led to the recruitment Robert Le Gall (fiddle/electric guitar). He and Le Berre after that became the primary of the group, with both composing and choosing the musical path. The music group’s 90s established Glen River became a nice, swinging collection using the overtones of the natural folk jig.
