L'Algerino was introduced to rap at a very young age listening to NTM and IAM in the northern districts of Marseille. He started rapping at the age of 11 and quickly began releasing mixtapes and appearing in local concerts. He had brief stints with groups B-Vice Junior and 45 Niggaz, releasing independent albums with both of them. He officially made a name for himself when he appeared on Psy 4 de la Rime's album Block Party, and then on Akhenaton's Black Album. He would later go on tour with IAM before releasing his debut album titled Les Derniers Seront Les Premiers in 2005 on the 361 Recordz label.
