I started as a Hardcore producer in 1994 as Cybernater vs Cybermaniac. This was until 2004. Several tracks have been released by me on the label the 5th Gear. These were released under the names "Northern Terrorizers, Dj Portos, Maniac M, Mr. X and Cybernater vs Cybermaniac". During that period I also performed as a live act at several small parties in Groningen! After not producing and performing for a long time since 2004, I started producing again from 2018! In March 2021, as DJ Portos, I released a first Release on the Digital Gabba Records label. In from 2021, six fat EPs have also been released on the Brutal Force Records label. And number of remixes for the label Rotjecore records in 2021 and 2022! This year I also continued with a second genre as a producer, trance. A first release will be released this summer! There are again some cool tracks in production by me and in collaboration with other cool producers! More coming soon!
