Jeckyll Hyde are a jumpstyle duo comprised of Dutch electronica producers Maarten Vorwerk and Ruud van Ijperen, also known as Ruthless Vorwerk, among many other monikers. The duo made their debut as Jeckyll Hyde in 2005 with the 12" EP Precious Dreamer, which they released on their own label, Square Beats. A second 12" EP, Kick This One, followed later in the year. Their third 12" EP release as Jeckyll Hyde, Frozen Flame (2006), was a mainstream breakthrough hit, reaching number ten on the Dutch singles chart. The commercial success of Frozen Flame was clearly tied to that of jumpstyle, an electronica music and dance style especially popular in the Netherlands at the time. The follow-up single Freefall was similarly fashioned and proved even more successful, topping the Dutch singles chart (indeed, it was the first wholly instrumental song to do so since 1989). In addition, Jeckyll Hyde also released a full-length album, The Album (2007), which went Top Ten, and another single, Time Flies, which went Top 20. ~ Jason Birchmeier, Rovi
