This didn't happen right away, however. In fact, Cocktail languished for months after being released in February. It wasn't until the car company Mitsubishi used "Tus Ojos" in a commercial that Belanova earned any substantial notice. Once "Tus Ojos" caught on, though, it caught on in a big way, becoming a chart-topper and driving Cocktail up the album chart to number five. Moreover, Belanova promoted the album heavily, performing concerts all over Mexico while issuing a couple follow-up singles ("Suele Pasar" and "Aún Así Te Vas," the former peaking at number eight, the latter at 12).
All of this initial success was far eclipsed by that of Dulce Beat (2005), Belanova's second album, which the band recorded in Buenos Aires with producer Cachorro López, who is perhaps best known for his brilliant work with Julieta Venegas. Dulce Beat resembles Cocktail in style -- thoroughly contemporary disco-pop with feel-good lyrics written and sung with charisma by Guerrero -- yet it's somewhat more accessible, no doubt with the teen market as well as increased international appeal in mind. The lead single, "Me Pregunto," was released to Mexican radio in May and went on to spend five weeks atop the Top 100 airplay chart. Moreover, it was a Top Ten hit in Chile and Argentina, setting the stage well for "Por Ti," the second single from Dulce Beat. It took only three weeks for "Por Ti" to rocket atop the Mexican airplay chart after its October release, and it remained in rotation on radio and MTV well into the summer of the following year. Around the time Belanova finally released a third single from Dulce Beat, "Rosa Pastel," they also reissued the album itself, retitling it Dulce Beat 2.0 and adding a bonus disc of acoustic versions and remixes. (As with the standard edition, this re-release didn't get issued in the States until months afterward.) As 2006 came to a close, Belanova garnered a Latin Grammy nomination for Dulce Beat (Pop Album by a Duo or Group with Vocals, ultimately awarded to La Oreja de Van Gogh for Guapa) and López also garnered a nomination for his work on the album (Producer of the Year, which he took home). ~ Jason Birchmeier, Rovi
