Born in Buenos Aires (Argentina), Javier spent his childhood in Caracas (Venezuela). This is where he started playing drums. Inspired by an incomplete 60's drumkit that was given to him by his dad's band mate, he began drumming at the age of thirteen. Javier studied drumming with Venezuelan legendary drummer Jose Mato. Soon after, he started Claroscuro, his first band. By the the age of seventeen Javier was already playing professionally. With Claroscuro, he recorded and released three productions: Claroscuro-EP (1993), El Viaje de Una Vida (1995) and Supereterodino (2000). They toured extensively sharing the stage with artists such as Alanis Morissette, Soda Stereo, Molotov and Aterciopelados.
