Danish/Norwegian Helden-tenor John Olsen has studied with Tina Kiberg, Stig Fogh Andersen, Tonny Landy and has attended several masterclasses with Linda Watson, Gregory Llamar, Dagmar Aschellenberger among others.

John is with his warm and charismatic baritonal tenor voice a rare find. Born for the dramatic parts of Siegmund and Parsifal, but with a sense of comical talent as well, he has, among other things, taken part in Danish composer Børresen's one-act opera "The Royal Guest" and in Weyse's "The Sleeping Draught" in Denmark. In the 2019/20 season, he sang in Mozart's "The Magic Flute" at Theater Chemnitz in Germany, where in 2021 he should have debuted in the roles of Siegmund in "Die Walküre" and Max in "Der Freischütz", but unfortunately it was canceled due to the pandemic. In 2022, he sang the part of the third jew in Bergen Philharmonic's "Salome", both in Bergen and in Edinburgh, and he returned to Bergen in January 2023 in "Parsifal" as cover for the title role and as dritte Knappe. He has also sung Siegmund, Otello, Eisenstein and more, in excerpts at concerts and has been a part of several professional musicals as well. 

John is a true Siegmund of Die Walküre or the title role of Parsifal but is also studying the title role of "Otello", Canio in "Pagliacci", Florestan in "Fidelio" and Herodes in "Salome".
