Fault retro-fixated hipsters like Beck. Or kitschy shag-osaurs like Austin Powers. But no matter who's to blame, the musical madness of Brazil's late-'60s Tropicalia movement broke big in '99. The success of the era's veterans -- Tom Zé, Caetano Veloso, Gilberto Gil, and Os Mutantes all put out acclaimed albums this year -- has rekindled interest in a moment of postmodern pop in the midst of the steamy tropics. TROPICALIA ESSENTIALS gathers the seminal works of sonic cut 'n' paste that merged acid rock with Brazilian folklore in effort to shock conservative '70s Brazil into the 20th century. Best of all, these essentials don't overlook the non-marquee players in the Tropicalia opera: Nara Leão and visionary producer Rogério Duprat get theirs along with Gil, Veloso, Gal Costa, and the Mutantes (there's no example of Zé's avant-garde compositions, however). An excellent starting point, these essentials neatly fill in where Tropicalia's hard-to-find original documents leave off.
