The London Mozart Trio Chamber Ensemble is a small critically acclaimed group of professional chamber musicians, international soloists in their own right who perform together as a duo, trio, quartet or quintet as repertoire demands.

At the heart of the Ensemble is the Trio, which comprises Colin Stone (piano), Krzysztof Smietana (viola) and Sagi Hartov (cello). Completing the Ensemble are Dimitar Burov (violin) and David Greenlees (viola). Together they play recitals of Haydn to present day at music festivals and clubs throughout the UK and abroad. Most recitals are engagements by concert promoters, but the Ensemble also promotes its own concerts, notably at central London venues, such as Wigmore Hall and St John's, Smith Square, as well as in Harrow in N. W. London, where the Ensemble bases itself.

The Ensemble is a registered charity (no. 1088320).
