In their music, Irene sings mezzo soprano vocal, and Ellen supplies soprano harmony, with Irene on guitar and Ellen playing the 5-string banjo in a traditional up-picking technique. Their performances are notable examples of close harmonies singing."@en . "1956Z"^^ . . . . . . . "Kossoy Sisters"@en . "group_or_band" . .
