Based in Germany, the electronic production duo of Marc Et Claude consists of Marc Romboy and Klaus Derichs. The two also co-own the label Alphabet City, which houses such artists as Ferry Corsten and Future Breeze. The two started producing seriously during the explosion of German trance in the mid- to late-'90s. Their first release, "Toulouse," was on their own label, Le Petit Prince Records. In 1997, the duo teamed up with Jurgen Driessen and produced the track "La," which went to the top of the German dance charts and helped them crossover to U.
