Ontborg was founded from the ashes of the band Voices Of Decay in 2017 by three former members to take a new direction with Scandinavian Death Metal. The band remembered their own metallic roots to create their own sound and indulging their blazing fondness for bands like Dismember and Benediction.

In 2019 the band released their full lenght debut "Within The Depths Of Oblivion", a ten track piece, which received very good reviews in the press all over the world. The cover artwork was created by Juanjo Castellano.
