Probably one of the most distinguished Bach tenors from the twentieth hundred years, Kurt Equiluz began his performing career while soloist using the Vienna Kids Choir. After research in music theory, harp, and performing in the Austrian Condition Academy for Music and Artwork in Vienna, he received several major contests, like the International Performing Competition in Britain (1947-1948) as well as the Vienna Mozart Competition (1949). He became a member of the Vienna Condition Opera Chorus in 1950 and continued to tell apart himself in 69 different tasks, including Pedrillo in Mozart’s Die Entführung aus dem Serail, Don Curzio in Mozart’s Le nozze di Figaro, Scaramuccio in Strauss’ Ariadne auf Naxos, Balthasar Zorn in the Wagner’s Die Meistersinger, Spoletta in Puccini’s Tosca, Kaiser Altoum in Puccini’s Turandot, Monostatos in Mozart’s Die Zauberflöte, and Rossillon in Léhar’s Lustigen Witwe. In 1987, he offered his final overall performance within the opera stage in Gluck’s Iphigénie en Aulide. Having a vocal design suitable to oratorio and lieder, his status mainly rests on his shows in the entire routine of Bach cantatas and Passions aimed by Harnoncourt and Leonhardt. In 1971, Equiluz was was appointed as teacher in Musikhochschule of Graz, and in 1982 as teacher in the Wiener Musikakademie.
