Junkie XL

Tom Holkenborg (born December 8, 1967 in Lichtenvoorde, Gelderland, Netherlands), better known as Junkie XL, is a Dutch multi-instrumentalist, producer, and engineer. He uses the name JXL in cases where the term “Junkie” might cause offense. Says Holkenborg of his name, “I called myself Junkie XL from the point of view that once you’re completely overworked, you never want to go there again. The ‘XL’ stands for expanding limits; broadening up your vision.”
