He began performing in Parisian clubs with his Trio, while occasionally producing remixes for the DMC label (Electro) with DJs Tom and Jerry Bouthier.
After numerous experiences arranging choirs and orchestras, and composing for several illustration music collections (Koka Media, Gum), Julien Agazar crossed paths with Manu Dibango, becoming his pianist and musical director for over fifteen years.
He has accompanied French and international artists such as Manu Dibango, Richard Gotainer, Asa, Keziah Jones, Cunnie Williams, Oumou Sangare, Jad Wio, Michel Fugain, Mayra Andrade, Calypso Rose, Ayo, Maceo Parker, Ana Tijoux... to name but a few.
For more than ten years, he has been composing for images. Notably for television, with the series Duel en Ville (P. Chaumeil - France 3) or the documentary Floris (J. Kalimunda - TV5 Monde).
But also for digital(Culture Club - C. Robb) and advertising(M6 mobile - La Vache qui Rit). He also composes for theater: Eby et la Petite au Bois Dormant (S. Mesguich ) and Aujourd'hui c'est Ferrier (J. Ferrier).
