Dälek undermine the simplistic gloss of mainstream rap with gritty, complex underground hip-hop that at once clicks and whirs like some electronica head trip, layers on environmental ambience, and assaults the listener with aggressive, intelligent rhymes. Recalling the Bomb Squad's innovative production style but pushing further into the avant-garde, Dälek took the industrial hip-hop sound of the '80s and '90s to its extreme, paving the way for noise-rap groups like Death Grips and clipping. Making their debut with 1998's Negro Necro Nekros, Dälek toured heavily and released widely acclaimed, challenging albums like 2002's From Filthy Tongue of Gods and Griots and 2005's Absence, additionally collaborating with Faust, Techno Animal, Kid606, and many others. After a brief hiatus during the early 2010s, the group re-formed with an updated lineup, and their release schedule continued with confrontational, boundary-pushing albums such as 2017's Endangered Philosophies and 2022's Precipice.
