Zulya Kamalova presents 'What a voice!' An exploration of the human voice in its countless capacities, from highly technical to extremely emotional, from forced to effortless, with a big band or acapella, for money or for fun.
A look at interesting techniques and remarkable singers, both famous and obscure, from Diamanda Galas to Maria Callas; from forest pygmy music of Cameroon to Soviet Army choirs.
