Andy & Lucas
These boys aren't just in a band together; read their bio and it sounds like they're joined at the hip. Born and raised in the same barrio -- La Laguna -- of the Spanish city Cardiz, the boyhood friends attended the same college, studied together religiously and even listened to the same music as they grew up. So it came as no surprise when their 2003 debut showcasing their tight ensemble singing . But really it was their flamenco-pop mishmash that garnered them award after award in Spain and made them instant stars. To see two fresh-faced young guys singing like they were hardened flamenco veterans -- and then straightening up to drop some pop balladry -- is nothing if not endearing. The duo released their follow-up, Desde Mi Barrio, in 2005.
