As the band began to lose its momentum, Calogero decided to launch himself as a solo artist and gathered important connections by writing songs and collaborating with already popular artists such as Zazie and Pascal Obispo. The latter helped produce Calogero's first solo album "Au milieu des Autres" (2000). His second album, "Calogero" (2002) was a huge success with the hit singles "En apesanteur" (In Weightlessness), "Aussi libre que moi" (As Free as Me), "Tien an men" and "Prendre racine" (To Take Root). Finally, in 2004, Calogero released "3", featuring "Face à la mer" a duet with French rapper Passi and several other top singles such as "Yalla" and "Si seulement je pouvais lui manquer".
