SY11 Events

SY 11 Events Ltd. was set up in 2020, when Sonya Yoncheva decided to produce her own concerts instead of appearing only as someone else's guest; the first of them was staged at the Roman Theatre in Plovdiv. The company works chiefly in Bulgaria — gala evenings on Alexander Nevsky Square in Sofia, the Inmost Voices series in Bulgaria Hall, concerts in Plovdiv — and in October 2025 brought Operalia, Plácido Domingo's competition, to Sofia for the first time. Yoncheva runs it herself, and her own recordings and singing partners supply much of the programming.
