For their 30th anniversary Lena and Mädir entirely dedicated themselves to the production and tour of Beautiful Turns, a manifestation of the Nouveau Cirque concept.If you decide to skip through because you don't have time to enjoy the full 12-minute display of skill and strength, be sure not to miss the very end. Another performance is recorded here.
