In 2013 the Concertgebouw organizes an anniversary series with each month being devoted to one decade in the past 125 years. Alongside these twelve chronological concerts a fringe programme will also take place. Ammodo is supporting two contemporary concerts as part of this series to be performed in the Great Hall: Threepenny Opera by Kurt Weill and Spring Symphony by Benjamin Britten. The support is intended to contribute to two special pieces of music from the 30s and 40s, performed in the Concertgebouw.
