Javier Rosas y Su Artillería Pesada are one of the most roots-oriented bands on the alterna-corrido scene. The sextet delivers deft narcocorridos and outlaw songs in a pronounced Northern Sinaloan style. Frontman Rosas is also the band's chief songwriter. He was born in Sinaloa in 1992, and has been singing all his life. The band came together in the Sonoran desert in Ciudad Obregon in 2010.
