In January 2016, the famous period-performance group, Tafelmusik (Toronto) (same as the legendary 1989 recording of Missa Dei Filii/Litaniae Lauretanae 'Salus Infirmorum') held a competition for upcoming vocal soloists. They had to sing a selection of arias from Handel, Bach and Zelenka. The winners were announced, and they will be singing in a concert of Bach & Zelenka, along with the great Baroque specialist soprano Dorothee Mields (her first time with our Czech master?), and conducted by Ivan Taurins.
