While living in New York Skúli still kept close relations with his fellow musicians in Iceland. For the release ‘Sería’ he originally formed a group that brought his closest collaborators in New York: Anthony Burr, Eyvind Kang and Amedeo Pace together with upcoming Icelandic artists; HildurGuðnadóttir, Jóhann Jóhannsson and Ólöf Arnalds, all of whom he later created meaningful and lasting work relationships with, touching many exceptional works such as Ólöf’s debut Við og við, Jóhann’s scores for Sicario and Mandy and Hildur’s album Without Sinking.
When Skúli returned to Iceland he started Mengi, a performance space that has since become a central place for creative music in Reykjavík. Skúli has worked with the Icelandic Symphony Orchestra both as a performer and composer. Other notable Icelandic collaborations in the recent years include Víkingur Ólafsson, Megas, Shoplifter, HAM and Bára Gísladóttir.
