Petr Kotik – No Agency

"The World" is the new online project of the Ostrava Center for New Music. The aim is to get new music to the people even in these times. Over the next three months, video / audio recordings of solo compositions performed by members of the international Ostravska banda and soloists who have been cooperating with OCNM for a long time will be published exclusively every week. The first video is of a new composition by Petr Kotik, and was made in collaboration with the S.E.M. Ensemble.

50 Years of the S.E.M. Ensemble – POSTPONED

This video has been uploaded to make up for the postponement of the "50 Years of the S.E.M. Ensemble" event, which was due to take place on April 1st, at the Czech Center in the Czech National Building in Manhattan. For more information on the Czech Center and this project, follow the link here.

We look forward to rescheduling this concert once conditions allow.
