Since Herbert von Karajan brought him to the Salzburg Festival, Francisco Araiza has become one of the world’s most demanded interpreters on the great opera and concert stages, particularly at the Bavarian State Opera in Munich, Zürich Opera House, the Vienna State Opera, which in 1988 recognised him as its then-youngest “Kammersänger”, and the Metropolitan Opera New York.

Following legendary interpretations of Mozart and Rossini, from the mid-1980s he sang the lirico-spinto roles in the operas of Verdi, Puccini, Massenet, Gounod and Wagner, to great acclaim. His commitment to the education of young singers is apparent through not only his masterclasses, but also his namesake foundation in Mexico City, as well as his activity as juror in international singing competitions. Since 2003 he has held the post of professor at the State University of Music and Performing Arts Stuttgart. At the International Opera Studio Zürich, he teaches vocal and stylistic development, and is active within the structure of the Bertelsmann Foundation “Neue Stimmen,” as well as juror on the board of that competition.

Furthermore, he is a member of the foundation board of the “Liz Mohn Kultur-und Musikstiftung” in Berlin, as well as of the European Foundation “Europamusicale” in Munich, and the SIAA Foundation in Liechtenstein. He was artistic director of the Internationale Hugo-Wolf-Akademie and founded the foundation “Neue Meister der Liedkunst” in 2009. In 2011, the Instituto Nacional de Bellas Artes granted him its gold medal to recognise his four-decade-long international singing career.
