Tom Holkenborg, known as Junkie XL or occasionally JXL, is a Dutch multi-instrumentalist, producer, and engineer. He uses the name JXL in cases where the term "Junkie" might cause offense.
Holkenborg has collaborated with Klaus Badelt for Catwoman as a composer (uncredited) and producer for additional music and with Oscar-winning composer Hans Zimmer for Christopher Nolan's The Dark Knight Rises. He has collaborated with Zimmer again for Batman v Superman: Dawn of Justice. He also composed the score for Justice League.
