His greatest success was the second single "Au Nom de la rose", released in 1999, which was both number one in France and Belgium (Wallonia) for several months. Le Crabe est érotique, his first and only album to date, hit success being ranked among the best-selling albums in France from May to August 1999 (11 weeks, reaching number 11). In September of that same year, Moos released his third single "Délicate Chatte", but the song failed to follow up the success as the video was censored and never shown on television.
