After studying singing and the harpsichord at the Mozarteum in Salzburg, Aco Bišćević made his debut at La Scala in Milan, where he performed under the direction of Ingo Metzmacher. Bišćević has appeared as a guest at the Komische Oper Berlin, the Regional Theatre in Innsbruck, the Styriarte Festival, the Valle d’Itria Martina Franca, the Maggio Musicale Fiorentino and the Trame Sonore Mantua.

He has worked with conductors such as Michael Hofstetter, Theodor Guschlbauer, Jordi Savall, Reinhard Goebel, Vittorio Ghielmi, Federico Maria Sardelli, Václav Luks and Michael Curney.

With his haute-contre voice, Bišćević is a much sought-after concert singer.
