In his youth, Daði practiced drums and studied piano and bass guitar. He co-founded the band RetRoBot with his friend Kristján Pálmi. Later, singer Gunnlaugur Bjarnason and guitarist Guðmundur Einar Vilbergsson, whom he had met at the South Iceland Multicultural School, joined the band. In 2012, the band RetRoBot won the Músíktilraunir ("Music Experiments") and Daði was chosen as the best electronic musician of the year. RetRoBot released one album, Blackout, a year later.
