At the age of 14, Gary Gehlen was already playing his first turntables in his parents' garden in Kelmis / Belgium for friends and family. His audience quickly grew and by the beginning of 2000 he was already playing in Graffitiy / Belgium, Abraxas / Germany and Castle of Love / Netherlands. In 2013 he became resident in the Loft Club / Aachen whereupon he was able to develop his own style in the following two years; varied-funky deep-house with oldschool techno sound. In the years that followed, he played his sets in other clubs and festivals, in the border triangle of Belgium, the Netherlands and Germany. In electronic music, he was able to fully live out his fascination for music and so he started producing in 2018. Dennis Engelhardt, previously known as Dennis Slim, is not a blank slate in the German and the European techno scene. He grew up in Berlin and spent his youth near Antwerp before moving to various places in Germany. In 2016 he and his family moved back to Belgium in Wallonia, near the border from Aachen. His passion for DJing began in 2006, and later he achieved first places in the technocharts with his productions thanks to his determination. His style of music developed further with him and so everything from Darktechno to Melodictechno was produced and played by him. As the label owner of “Dark Celebrate Recordings” and “Moon Rocks Recordings”, he can look back on many works with various artists as well as his own productions over the past decade.
