Klubbheads (Koen Groeneveld & Addy van der Zwan) is a team of dance music producers and DJs from the Netherlands. They have more than 40 aliases for their recordings, including Hi_Tack, DJ Disco and Drunkenmunky.
Koen Groeneveld (DJ Boozy Woozy) and Addy van der Zwan (Itty Bitty) first worked together in the Turn Up The Bass series of commercial mixes. They started producing music in the 1990s before meeting up with Jan Voermans (Greatski) in 1995. The trio created the sublabel Blue Records for parent Mid-Town Records to release their tracks as Klubbheads. In 1996, they had their first mainstream chart hit with “Klubbhopping”, which reached #10 in the UK Singles Chart in May. It was followed up with two other entries into the Top 40, in August 1997 with “Discohopping” (#35) and in August 1998 with “Kickin’ Hard” (#36). In 1999 they co-produced “The Launch” for compatriot DJ Jean, reaching #2 in September. At this time they also split up from Blue Records to found the label Digidance.
