Anna Larsson has, among other roles, achieved international recognition and status as the world's foremost exponent of Erda, with her rich, melliflous, "dark velvet" voice, in Wagner's Der Ring des Nibelungen, with perfomances at operahouses in Berlin,Vienna, Munich, Salzburg, Aix-en-Provence and Stockholm, and successfully created the roles of Waltraute, Orphée, Fricka and Dalilah at theaters including Bayerisches Staatsoper München, Festspiele Salzburg and Aix-en-Provence, Teatro Maggio Musicale Firenze, Palao des Arts Valencia, Royal Opera Copenhagen , Finnish National Opera and Royal Opera Stockholm, with many distinguished conductors- Barenboim, Mehta, Welser- Möst, Rattle, von Dohnany, Segerstam, and Nagano.

In concert, Anna is rightly justifying her position internationally as the premier, and most consumate interpreter of Gustav Mahler's works. She regularly sings with all the great orchestras- Berliner Philharmoniker, Lucern Festival Orchestra, New York Philharmonics, Wiener Philharmoniker, Chicago Symphony, Los Angeles Philharmonics, London Symphony and London Philharmonic orchestras.

She sings almost the entire concert repertoire for contralto and orchestra, with the most illustrious conductors including Abbado, Mehta, Salonen, Rattle, Dudamel, Pappano, Osawa, Masur, Maazel, Gilbert and Harnoncourt. Her extensive repertoire ranges from Handel's Messiah thro' Elgars Sea Pictures, Gustav Mahlers all songcycles and Verdi Requiem, to contemporary music.

Anna was nominated for a Grammy 2005 for the recording of R Strauss "Daphne", with Westdeutsche Rundfunks Symphonieorchester conducted by Semyon Bychkov.
