By January 2021, the Iceland Symphony Orchestra released the recording Occurrence on the record label Sono Luminus. It was performed by the ISO and featured Pekka Kuusisto "leading the violin concerto that Daniel Bjarnason wrote for him," with Bjarnason conducting. The album contains compositions by Anna Þorvaldsdóttir, Haukur Tómasson, María Huld Markan Sigfúsdóttir and Páll Ragnar Pálsson, and features the soloists Sæunn Þorsteinsdóttir and Víkingur Heiðar Ólafsson. After being last nominated in 2009, the ISO was again nominated for a Grammy in 2021: for Best Orchestral Performance for Concurrence at the 2021 Grammy Awards, losing to the Los Angeles Philharmonic.
