Karsten Mewes began his career at the Hans Otto Theatre in Potsdam, the Staatsoper Berlin and the Komische Oper Berlin, where he sang nearly all the major lyric baritone parts such as: Silvio, Papageno, Count Almaviva, Figaro, Fluth, Marcello, Lescaut, Posa, Ford, Iago, Macbeth, Scarpia and Rigoletto. His start in the Wagnerian Fach began with Melot in "Tristan und Isolde", Klingsor in "Parsifal" and the Flying Dutchman. He then progressed on to sing Alberich, Wotan and the Wanderer in Martin Schüler's Ring in Mannheim, where he had made his debut as Hans Sachs in 2010.
Throughout his operatic career Mewes has continued to dedicate his "spare time" to singing oratorio and concert repertoire. His performances of Carl Orff's "Carmina Burana" (Madrid and Tel Aviv), Bach's "B Minor Mass" (Madrid), Mahler's 8th Symphony (Graz and Peking), and Beethoven's 9th Symphony (Greece, Japan, Australia) have brought him acclaim worldwide.
Mewes has had the good fortune to collaborate with numerous renowned directors such as: Christoph Schlingensief, Harry Kupfer, Ehrhard Fischer, August Everding, Christine Mielitz, Jonathon Miller and Andreas Homoki. He has sung under the baton of: Sir Roger Norrington, Sir Colin Davis, Professor Reuter, Daniel Barenboim, Fabio Luisi, Simone Young, Donald Runnicles, Friedemann Layer, Constantin Trinks, Karl-Heinz Steffens and Dan Ettinger.
By the personal request of Christoph Schlingensief Mewes was invited to sing Klingsor in the Bayreuther Festpiele production of "Parsifal".
Last season he sang Scarpia, Ankarström, the Speaker, Jochanaan and Telramund at the National Theater in Mannheim, where he can be seen singing Wotan and the Wanderer until 2013.
