This year songs in Livonian were recorded from two singers in north western Kurzeme. There are no later recordings of singing in LFK featuring this Finno-Ugrian language. Still there is a quite long fragment of conversation in Livonian between Valda Suvcane and Viktors Bertholds recorded in summer 2003 (a sample is available here).

The two mentioned above singers were:

Hilda GrivaHilda Griva, (maiden name Cerbaha), born in Sikrags 1910., died 13 September 1984 in Ventspils. Her father was a Livonian, mother - Estonian, the family used both languages, Hilda learned also the melodies of both nations. She also studied music, worked as a teacher of music, established and led the Livonian group "Kandla".
Katrina Krasone

Katrina Krasone (maiden name Fletno), born in Kosrags 22 August 1890, died 1 June 1979. She sings without any musical education, in a
characteristic folk style. Katrina was also featured in the film by Andris Slapins "Livu dziesma" ('Livonian Song'). Although her farmstead is gone, the birch tree planted on her birthday still grows proud and mighty.

The songs recorded then are available on a CD. CD vaks

Interesting that the same song has been recorded by Emilis Melngailis many years before from Marija Saltjare.

Marija SaltjareMarija Saltjare (maiden name Bertholde) was born in Pitrags in 1860, died in 1930. She has been among the best Livonian informants of the time, recorded also by Estonian adn Finnish scholars. She has narrated more than 200 folk-tales and legends and sung more than 90 songs (the collection is kept at Estonian folklore archive in Tartu). Listen what it sounds like according to Melngailis notes.
