In late fall 2019, common interests led to an beneficial artistic collaboration of the voice teacher and founder of the +PlusOpera Studio Vienna Sylvia Saavedra-Edelmann and David Holzinger.

During the crisis, which led many performing artists to the edge of their existence, the team found ways and possibilities to keep the opera studio and the voice coaching up and running.

They started a video production service for all voice students. A conducting David Holzinger was filmed, performing the pre-ordered arias. Later the music was added to the video by the pianist Uliana Cheklina, a collaborative pianist of the team of the +Plus Opera Studio.

That way, students were presented with audiovisual material they could use for their coaching, instead of heaving to consult audio media only.

Planned concerts for the 2020 season and guest appearences with the INSO Ukraine in February and the Sichuan Symphony Orchestra Chengdu in April, among others, had to be postponed because of the measures taken by states in order to fight the pandemic.
