Páez released his debut album in 1984 and spent the rest of the decade exploring Latin America's dark political and social underbelly. He lightened up on 1992's career-defining El Amor Después del Amor (Love After Love), and has since released some two dozen albums ranging in tone from remarkable intimacy to wild abandon.
