Icelandic baritone Ólafur Sigurðarson has been hailed as “the best Alberich in the world” a title earned through electrifying performances across the globe - from Bayreuth to La Scala, where his portrayal in Das Rheingold was described as “flawless… his delivery felt natural, as if he were speaking rather than singing.”

In 2025/2026, he returns to the Teatro alla Scala for Ring des Nibelungen, following celebrated performances in the role of Alberich across Europe and in China at the National Centre for the Performing Arts in Beijing. He also stars as Simone in a new production of Violanta at Deutsche Oper Berlin and Telramund Lohegrin with Malmö Opera.

Sigurðarson has also appeared at the Teatro Comunale di Bologna as Telramund, with the Bergen Philharmonic Orchestra as Klingsor Parsifal, and with the Gothenburg Opera as both Rigoletto and Alberich Götterdämmerung.
