Zalem began to play the didgeridoo in 2001 with Denra dur, Ash dargan, Mark atkins and Gauthier as reference players. He first started with a wobble-based style of playing and progressively developed his own style with his electro-rock influences. In 2007 he entered the band JMPZ (rock/electro/tribal), and recorded with them the third album of the band and started a national tour. Thanks to this, he gained his professional status and let down his Biology studies to dedicate his whole time to music.
