Their tough-talking new name aside, the banda formerly known as Colmillo Norteno has the soul of a pop star. With its diverse range of high-octane rock-banda and Sinaloa-style slow jams, it's no wonder their debut (under that name) burned up the charts. This is a group that's not afraid to take risks: Check out the beachy, almost adult-alt "Quien Te Va Amar," which sounds like Mexican Jason Mraz. But they're also rooted in Regional Mexican tradition, from the whirling dervish accordions to the belching tuba to the growling, hooting, smoothly strutting vocals.
