Vienna calling: Strauss's 'The Blue Danube' to waltz into outer space

But the world famous waltz will truly travel among the stars on Saturday, when the European Space Agency's (ESA) antenna will broadcast a live performance of it into space to celebrate the composer's 200th birthday. The Vienna Symphony Orchestra will play a concert in the Austrian capital from 1930 GMT, Josef Aschbacher, ESA's director general, told AFP. The concert will be broadcast live on the internet and also be shown at a public screening in Vienna, in New York at Bryant Park, and near the antenna in Spain.
