Hardstyle project from Utrecht, Netherlands.
Started in 2004 as a duo of Willem Rebergen and Bobby van Putten under name Nasty D-Tuners. Nasty D-Tuners were signed to Scantraxx label in late 2005. Unable to keep the 'Nasty D-Tuners' name due to disagreements with the former label, the name Headhunterz was chosen. Later in 2006 Bobby van Putten decided to left, and the project became a solo project of Willem Rebergen. Rebergen's first solo performance as Headhunterz was the 2006 edition of the Q-Dance event, Defqon.1.
