Danish band Iceage started out as an abrasive punk rock quartet before exploring a more multifaceted approach to songwriting. The cold, abrasive, Joy Division-informed sound of early albums like their 2011 debut New Brigade quickly grew as the band expanded their concepts of instrumentation, arrangement, and atmosphere on more sophisticated outings like 2021's Seek Shelter. Iceage formed in 2008, led by singer and guitarist Elias Bender Rønnenfelt, guitarist Johan Suurballe Wieth, bassist Jakob Tvilling Pless, and drummer Dan Kjær Nielsen. The quartet, whose average age at the time was 17, had been friends for years before they began making an impression with their music.
