On 1990's Canción Animal, Argentine college rockers Soda Stereo hit upon something truly magical with a jangly, emotive sound that would spread like wildfire through Latin America's indie rock scene. Tracks like the electric guitar-heavy "Un Millón de Años Luz," the instant-classic guitar-pop anthem "De Música Ligera," and the beautifully layered "1990 (Mil Nueve Noventa)," with its shuffling beat and infectious piano solo, defined the band's sound for a generation of fans.
