Should you be following this blog, it's time for you to get to know Mercedes Sosa.  She's an argentinian singer (read about her on Wikipedia) who is one of the most influential musical figures in my life.  Why?  Aside from having a beautiful and expressive dark voice (almost tenor-like), and being a consummate performer, her choices of repertoire fit my favorite emotions during my teenage years and in my twenties.  

Of all her songs, one of my very favorites is Soy Pan, Soy Paz, Soy Mas, by the celebrated Argentinian singer / songwriter Piero.  This song shows off her sensibility, and both the sweeter and most powerful aspects of her voice.  Plus, the lyrics are beatuiful.    

There is a live version that I haven't been able to find in any store, and this album at Amazon.com has the song.  Unfortunately, iTunes doesn't carry it with Mercedes Sosa, but they do have it with Piero himself.
