Amos, I would like to contribute, but you know that I have never been in pure folk. I'm mainly a classical choral tenor in love with old spirituals and traditionals. Would some 70+ year old song, accompanied by piano, be ok ? Are these songs free from copyright hassle ? I'm thinking Amazing Grace, Shenandoah, or Love Song from Robeson's movie Sanders of the River (1930). If you prefer a typical Argentinean song, just tell me, but that could be out of the general orientation of the CD.I can obtain a technically good CD and MP3.
Un abrazo - Andrés
