On September 21, 2023, Mark S. Doss will sing the role of Giorgio Germont in La traviata, at the Wales Millennium Centre Cardiff for the Welsh National Opera, in a David McVicar production and under the musical direction of Alexander Joel. He will share the stage with Stacey Alleaume in the title role and David Junghoon Kim as Alfredo. There will be a total of fifteen performances through November 25, touring towns such as Llandudno, Bristol, Plymouth, Birmingham, Milton Keynes, and Southampton.

The American bass-baritone is a familiar name to the audiences of the Welsh National Opera, having already been greeted as Scarpia in Tosca and in the title role of Rigoletto, receiving rave reviews on both occasions.

This is the second outing as Germont for Mark S. Doss, who debuted the role in Hyogo, Japan.
