hardsl Dennis van Oenen aka Boom Service and Funk da System Oudleusen For bookings & info: email@example.com Born in 1976, Dennis a.k.a. Funk da System started producing music in the early 90's. Working as an editor for Dutch music magazine Strobe, he got in touch with a lot of well-known hardcore producers with whom he shared his ideas. This eventually resulted in the track No worries, a collaboration with Neophyte, and a solo release under the alias Boom Service on the Terror Traxx label. These first releases were followed by three EP's on Megarave and Dutch Gabber Network under the name Hard SL. The last EP called Scorpion Styles was made together with Italian dj Exagon and contained the track Hardstyle Suckaz. After that release Dennis took a break but kept spending time in the studio, working on a new and improved sound, occasionally taking a step away from hardcore techno. This resulted in a remix for London based grime MC Jamakabi in 2012. At the moment Dennis is working on a new hardcore release. This page will be the place where you'll find the very first previews as well as some previously released and unreleased Hard SL and Boom Service tracks.
