From the stranger backwaters of Country music, as featured in The Old American Barn Dance, 1953. Apologies for the hammy intro:
Inspired by their family and the sounds of the animals and birds around them, they developed an astonishing repertoire of high, haunting yodels and yips that soon had them winning talent contests all over central Minnesota.
An excellent compilation of women singers in early Country music, Flowers in the Wildwood, features a couple of tracks from the DeZuricks, plus songs from the likes of the Coon Creek Girls, Samantha Bumgarner, Moonshine Kate, and the inimitable Fred and Gertrude Gossett ("All the Good Times are Past and Gone"). Irresistible.
