Legobygger123 is the alias of Aske Holt Boisen (born 2006), a rapper and producer from the Vejgård district of Aalborg, and a member of the Danish collective brødrene grene. He makes all his own beats and moves freely between grime, digicore, drum-n-bass and roots reggae - sometimes within a single release. Since his debut in 2022 he has become a recognised name in the Danish underground, with tracks like "Vejgård rudeboy" and "Uhøflig" drawing crowds well beyond what the venues expected.
