Original: They have been referred to as Germany's most successful pop duo, and have had a number of hit singles reaching the top-5 in many countries.
Simplified: The duo came back in 1998 recording their materials based on what the demand was in central European music markets at the time in the late 1990s, which required their original 1980s mellow Europop sound to switch into 1990s up-tempo Eurodance.
