La Renga have been performing to sold-out stadium audiences to critical acclaim since the release of their debut album, Esquivando Charcos, in 1991. The core of the band is vocalist/guitarist Gustavo Napoli, bassist Gabriel Iglesias and drummer Jorge Iglesias, and together, they produce a frenetic, unrelenting hard-rock sound driven by heavily distorted guitars and thundering drums. Napoli's warm, gravelly vocals are always out front, lowering, at times, to a deep growl and ascending, at other moments, in dark triumph over rapid-fire riffs.
