The Netherlands - Hardstyle
Sven Sieperda first came into contact with the hardstyle genre at the age of 16 when he heard the music live at an event.
From 2008 to 2016 he formed the duo Psyko Punkz together with Wietse Amersfoort. In June 2016, Sieperda and Amersfoort announced in a YouTube video that Sven Sieperda would from now on concentrate on the production of Psyko Punkz songs, while Amersfoort performed alone and also helped with the production. One of the reasons for this decision was the birth of Sven Sieperda's daughter.
Contrary to the statement made in the video, Sven Sieperda left the Psyko Punkz project a little later. On 2 May 2017 it was announced that Sieperda would now be producing and performing as Keltek for Scantraxx.
On 2 July 2017 Sven Sieperda made his first appearance under his new alias Keltek at the Summer Festival in Antwerp, Belgium.
