Soon they were joined by Tony Farinelli (bass), Cesare Barbi (drums), and Alle Bartoli (DJ, programming), opening up the band's palette to accommodate classic guitar rock, hip-hop, and electronica elements. Their first single, "Sei Quella per Me," became a radio and video hit upon its release in May 2004, and a few months later it was followed by the album Mariachi Hotel, produced by DJ Luca Pernici. Rio spent the following two years touring, performing at a number of popular events and Italian festivals, most notably at the Campovolo mega-concert of Italian rock star (and Marco's older brother) Luciano Ligabue. Their highly anticipated second album, Terra Luna e Margarita, appeared in 2007. It was produced by Saro Cosentino (Franco Battiato, Peter Gabriel). ~ Mariano Prunes
