Alan Lomax traveled the world in search of folk music.  He recorded many individuals and groups in Louisiana in the 1930’s.  Many of these recording have been commercially released and make fascinating listening.  Lomax also founded the Association for Cultural Equity, a non-profit whose mission is “to explore and preserve the world’s expressive traditions with humanistic commitment and scientific engagement.”  They have posted Lomax’s lesser-known videos, including many taken of Cajun musicians in the 1980’s.  Musicians include Michael Doucet and BeauSoleil, aged Dennis McGee, Octa Clark and Hector Duhon, Dewey Balfa, and many others.  Makes fascinating listening!
