YoYoDancing

In the video below cellist Yo-Yo Ma and Chicago Symphony cellists break into spontaneous dance while playing Johann Strauss II's Blue Danube Waltz in the foyer of Chicago's Symphony Center. The cellists are all using The Block Strap, designed by Mike Block, to support their instruments.

Ma was at the venue in June 2016 to perform  'A Distant Mirror' with CSO cellists Loren Brown, Richard Hirschl, Katinka Kleijn, CSO principal cello John Sharp, CSO principal percussionist Cynthia Yeh, Silk Road Ensemble cellist Mike Block and percussionist Shane Shanahan, and guest cellists Jeffrey Zeigler and Ashley Bathgate.
