While Frankfurt's impressive skyline makes it easily recognizable as Germany's major financial center, the city has also played an important part in the history of German electronic music, a history irrefutably connected with the name of Sven Väth. Väth began DJing during the 80s in Frankfurt's 'Dorian Gray' where he teamed up with Michael Münzig und Lucas Anzilotti to found the group Off. The group's single 'Electrica Salsa' became a major chart hit in 1988 and Münzig and Anzilotti (later to become known as Snap!) invested their returns in the 'Omen', which was to become Frankfurt's main techno club until its closure in 1998. During the 90s heyday of techno the rivalry between Berlin and Frankfurt became the stuff of legend and while Berlin's techno style has always traditionally leaned towards the analogue, rough and soulful Detroit sound, the 'Sound of Frankfurt' has been strongly influenced by EBM and more melodic synth-pop. Frankfurt became Germany's capital of the trance style during the 90s, a sound that was pioneered once again by Sven Väth's labels Eye Q and Harthouse. Another huge influence on the city's electronic music scene has been Ongaku Music, founded in 1992 by DJs Heiko M/S/O and Ata, eventually spawning the successful Klang Elektronik / Playhouse group of labels. Further worthy of historic note is Planet Core Productions, a company operating between 1989 and 1997, which covered the more industrial side of techno with a plethora of sub-labels and acts like The Mover or Mescalinum United. Frankfurt has also been the home to the influential Force Inc. group of labels, which in recent years have operated out of Berlin.
