In 2006, on his own initiative, Maestro Slavil Dimitrov created the chamber choir “Shumen”. Later renamed “Simeonis”, the choir quickly gained popularity as one of the leading ensembles in Shumen.

The repertoire includes works from the Renaissance to the present day, works based on folklore, as well as works of world pop, rock and jazz music.
