Noah's Flood, a children's opera by Benjamin Britten, is the latest project of the Bat Kol youth choir. "Britten loved children voices and wrote for them a lot. He actually wrote for his nephews, who sang in boys' choir. We in Bat Kol enjoy singing Britten a lot," says the choir's director, Anat Morag. "Britten invented a new percussion instrument, flung mugs, for this piece. It is a real show in sounds." There are several choirs behind the name Bat Kol - the awardwinning major choir, consisting of girls aged 12-18, that tours the world and wins awards, and also a training-oriented younger choir. Girls from the Young Bat Kol choir will be representing animals on Noah's ark, while the teens of Bat Kol represent Shem, Kham and Yefet and their friends," explains Morag. Actor/singer Eli Gorenstein is Noah, while Anat Eyni, "who grew up in Bat Kol and now sings in opera," comments Morag proudly, is Mrs. Noah. The Israeli Chamber Orchestra accompanies this productionof the hour-long piece based on a mediaeval play, where Dudu Zebba's Hebrew translation uses fragments from prayer book and the Bible.
