Jonathann C.A.S.T., bad boy of 22 years old, starts to play synthetizer at 10, to mix at 14 and begins to mix at 15 in the biggest clubs of his area by lying about his age. He is influenced by acid music, techno music and industrial electro. 2000 will be the year of his first productions, he will take his own live act up the year after. After various live acts, in 2004, he will stop for a moment for him to put a lot in his music by organising some events like the E.D.C, where more than 35 national and international artists played in a place where 7000 clubbers came. In 2005, he comes back with his first maxi «Human Synthetizer E.P» and a track on the «Killers Hits From Hell» compilation with DAVE TARRIDA, AL FEROX and CHAOTIK RAMSES on the prestigious DANCEFLOOR KILLERS label, both of the maxis, which are electro/techno, really show his dark and brutal influences. Afterward, he plays in different places where he had the chance to be booked with such artists as WOODY MC BRIDE, AL FEROX, HUMAN BODY, MILLIMETRIC, VITALIC, ALEXANDER KOWALSKI, or KIKO. Jonathann was also playlisted by many artists, like The Hacker, for his track «Human Synthetizer E.P». At the beginning of 2007, waiting for the release of his new EP called «Acid Body Music» on KOBAYASHI RECORDS with an AL FEROX remix, Jonathann joined HELVET UNDERGROUND label for a first release with four tracks, called «Die By The Cross» and a participation on the eponymic compilation of the label. It is also the moment for him to make you discover his new live act full of new tracks.
