While a roaring ball stirs up spirits inside, a boy and a girl meet on the sidelines – and fall in love at first sight. But because they belong to warring families, Romeo and Juliet's love may be immortal, but it is above all forbidden. The chamber opera by the German-Baltic composer Boris Blacher, written in 1943, condenses Shakespeare’s famous tragedy to its essence: the fate of Romeo and Juliet. Scenic miniatures conjure a foggy world hostile to love. Characters occasionally materialise like ghostly apparitions, while a Brechtian chansonnier comments with humour and with harshness on the failure of the greatest love story of all.
