Karl got interested in DJ'ing back in the early 90's when as a kid he got his first go on a few 1200's with an old used and abused Dateq mixer at a friends place. Learned the ropes by playing his friends' collection of early (acid) trance, "turn up the bass" house music and early rave records at first, but eventually fell in love with techno music which lead him to buying his own records by the likes of Mauro Picotto, Jeff Mills, Dave Clarke and later some more work by Speedy J and Robert hood as being a bass head he slowly started to appreciate the more minimalistic, slower yet bass heavy sounds more than the fast, mid/high driven "rave style" techno music.

Now using a full hybrid live set-up that includes synths, samplers and DAWs, he's usually seen and heard in the greater Amsterdam area. He's also known as the 'Eindbaas' (dutch for End Boss) for usually being the final bad ass act of the night.

His sounds can best be described as deep, minimalistic, bass driven and hard.
