The BBC Proms - Prom 11 - Stockhausen

Last summer Graham Vick's Birmingham Opera Company transformed a disused factory in Digbeth into the fantastical world of Karlheinz Stockhausen's epic opera Mittwoch aus 'Licht' with two bactrian camels, four helicopters and a wash of yellow light.

Tonight Ex Cathedra and Jeffrey Skidmore revisit the Babel tower of the opera's most dazzling section, Welt-Parlament ('World Parliament'): a multilingual a cappella tour de force of extended vocal techniques.
