The singing of Netania Davrath was praised by reviewers who appreciated her fresh, young voice, and her use of the original dialect. Vanguard, as noted by Bob Coltman, re-released in cd format by Sony. There are 27 tracks in five Series, arranged by Canteloube in the 1920's. In 1955, Canteloube added fifteen more in a new series, making a total of 42, all covered on the Davrath set, originally released in 1963. The album booklet has both the dialect and translations for all songs. As far as I know, this is the only complete recorded set. Discontinued at the moment, but Amazon lists old sets for $7.99 up.
I also have a set by Kiri Te Kanawa, lacking the new series of 15, but I prefer the Davrath; Kiri's voice is a little too heavy for these songs (personal opinion only).
