Andreas Bauer Kanabas sings important roles in the serious bass repertoire in eight different languages. Verdi and Wagner roles occupy a large part of his repertoire, as do Russian roles. The wide range, soft timbre and legato culture of his voluminous voice make him a bass singer with great versatility.

His repertoire includes Filippo II (in Italian and French), Zaccaria, Fiesco, De Silva, Banco and Padre Guardiano, as well as Gurnemanz, King Marke, King Henry, Landgrave Hermann, Pogner and Daland.

He also sings the title role in Duke Bluebeard's Castle, Vodnik/Rusalka, Gremin/Eugene Onegin, Ibn Hakia and King René/Iolanta, Boris/Lady Macbeth of Mtsensk, Pimen/Boris Godunov, Claggart/Billy Budd, Mephisto in Gounod's Faust, Escamillo/Carmen, as well as Sarastro, Osmin, Komtur and Baron Ochs/Der Rosenkavalier.
