Under Cover: Luiz Gonzaga

Everybody covers Luiz Gonzaga, because he wrote totally irresistible songs: accordion-heavy party music for Brazil's dusty countryside. (He was like your cool old grandpa who picked up an accordion practically before he could walk.) But when he gets covered, look out—there's no telling what might happen. Seriously, you're as likely to hear polished pop as you are out-there ‘70s experimentalism.
