That country is, of course, Argentina. Why Argentina, you ask? Well, for one, my girlfriend is Argentinian and I don't have much of a choice in the matter. That's about it, but it's the first year I've actually been excited about it, so I don't mind. All that aside, Al Lado del Camino is a beautiful song with a lot of autobiographical elements about Fito's life mixed in with some social commentary. This is one that I'd recommend taking a look at the lyrics for; they're very poetic and complement the music in a way that blends the two elements into a unique work of art.
