Bjarnason maintains a close connection with Los Angeles Philharmonic, having written From Space I Saw Earth for Gustavo Dudamel, Zubin Mehta and Esa-Pekka Salonen to conduct together at its Centennial Birthday Celebration Concert and Gala in 2019. In 2017 they premiered Bjarnason’s Violin Concerto with Pekka Kuusisto at the Hollywood Bowl, in a co-commission with Iceland Symphony. This was part of the orchestra’s Reykjavík Festival, an eclectic and multi-disciplinary 17-day event, curated by Bjarnason, and in which he featured as conductor and composer.
The Violin Concerto, which is titled Scordatura, became a success with audiences and orchestras and remains very popular. Kuusisto has performed it with Philharmonia Orchestra, Orchestre de Paris, New York Philharmonic, Detroit Symphony, National Arts Center orchestras, Swedish Radio and Finnish Radio symphony orchestras, Göteborgs Symfoniker, MDR Sinfonieorchester and NDR Elbphilharmonie. Bjarnason conducts the recording of the work with Kuusisto, as part of the final instalment of a three-album recording project with Iceland Symphony for Sono Luminus focussing on Icelandic music and composers.
In 2023, Bjarnason was named Guest Artist in Residence at Copenhagen Opera Festival, where a co-production of his opera, Brothers, was performed. Originally co-commissioned by Den Islandske Opera and Malmö Opera the opera was premiered in 2017, by its lead commissioner, Danish National Opera, and directed by Kasper Holten. Brothers is based on the Susanne Bier film of the same name, was also revived in Reykjavík by The Icelandic Opera in 2018, and subsequently opened Budapest’s 2019 Armel Opera Festival.
Bjarnason conducted the world premiere of Jóhann Jóhannsson’s Last and First Men, a multimedia work narrated by Tilda Swinton, at the 2017 Manchester International Festival with BBC Philharmonic, and subsequently at the Barbican with the London Symphony Orchestra the following year. Bjarnason also conducted Iceland Symphony Orchestra on Deutsche Grammophon’s latest release of Jóhannsson’s music.
A recipient of numerous accolades, in 2018 he was awarded the Optimism prize by the President of Iceland, won the 8th Harpa Nordic Film Composers Award for the feature film Under the Tree, and was nominated for the Nordic Council Music Prize. He also won Composer of the Year, Best Composer/Best Composition and Best Performer at the Icelandic Music Awards in recent years.
