Duelo may officially be a norteno outfit, but their soul is pure pop. Vuela Muy Alto is riddled with bubblegum hooks, sensitive heartthrob vocals and emotive melody lines that land somewhere between pop, R&B and mainstream country. It's just that all that poppy goodness happens to be sandwiched in among conjunto rhythms and accordion strains. Tracks like "Mueres de Ganas" are straight-up pop tunes (with accordion skeletons), and good ones at that. But Duelo are at their best on cuts like "Si Tengo Que Olvidarte," which start with a strong norteno structure and build pop layers into it.
