“Seiltänzer” – a concert performance that looks for the virtuosic-ecstatic and the clownish-tragicomic elements in the music of Stravinsky, Gubaidulina, and Paganini, that invites you with movement theater, dance, and artistry into a world of musical, poetic images and the magic of circus – and of course, risk. Because you must go out on the tightrope.
