John Otto Lundgren (born 12 October 1968) is a Swedish dramatic baritone opera singer.
Since then he has frequently been singing in stagings in The Royal Danish Theatre, e.g. Enrico Ashton in Lucia di Lammermoor, Posa in Don Carlos, Amonasro in Aida, Scarpia in Tosca, Kurwenal in Tristan und Isolde, and the title role of Der Fliegende Holländer.
In 2005, he sang the part of Prospero in The Tempest by Thomas Adès and four roles in one and the same opera – Cecilia and the Monkey King by Reine Jönsson in Drottningholm (Sweden).
In 2016 he also expanded his classical dramatic baritone repertoire by singing Wotan in Bayreuth, repeating that part in Stockholm in a single revival of the 2006 staging of Der Ring des Nibelungen directed by Staffan Valdemar Holm.
In autumn 2017 John debuted at the Dutch National Opera as Simone[3] in Eine florentinische Tragödie.
