Gustavo Cerati

Cerati, formerly of Soda Stereo fame, took home two Latin Grammies for this 2006 album, and it's not hard to hear why. This may not be genre-breaking rock, but fans will find Cerati's unreserved embrace of guitar-driven grind deeply satisfying -- and the guy still knows how to pen a melody. As the album wears on, he turns on his singer-songwriter credentials, slowing it down with "Adios" and "Lago En El Cielo."
