Jarno & Carl-oz were both dj-ing for several years when they started to perform as a duo (1996), under nicknames like "DrumTechAlliance" (breaks-drum'nbass) and "Johann O meets PervyBill" (electrobreaks) they performed at various parties in the dutch dance-scene. In 2001 they started up a new project to see if they could give there dj-perfomances a bit more creativity. Under the name of "Los dos Hermanos" they started to perform with 4-decks / 2-cdj-players and 2-pioneer mixers, trying to create a more cross-over mixture of house-music, techno, electro and breaks. Los dos Hermanos play on a monthly based residency at the well visited Audiocouture nights in Gigant Apeldoorn.
