I got this to compare with Nolwenn Leroy's cover versions of Tri Martolod, Jument de Michao and Dans les Prisons de Nantes. Glad to find these just as memorable. Okay, as a Brit I only catch the gist of the French songs and none of the Breton but that doesn't spoil the enjoyment. The more modern (1981!!) The Sun is Green title track is an epic 20min affair, only let down by a fadeout instead of a proper end.
4 albums at this price? Nothing to lose, well worth a try.
