Although the world knew precious little about Afro-Peruvian music when Susana Baca appeared on the seminal Soul of Black Peru, it was obvious that the plaintive voice behind "Maria Landó" belonged to an artist bigger than her local traditions. Apart from her striking delivery, there was the song itself, a hymn to social justice in the vein of Mercedes Sosa, Caetano Veloso, or Silvio Rodriguez, titans of Latin American song to whose ranks Baca would soon ascend. With the moving live document Espíritu Vivo, Baca at times moves so far beyond her native landó, festejo, and alcatráz that she and her accomplished band create their own unique fusion. Guest appearances from downtown New York jazzbos Marc Ribot on guitar and John Medeski on keys add to the experimental flavor. On the concert favorite Se Me Van Los Pies, Ribot plies a James Brown funk riff; versions of Mongo Santamaria's "Afro-Blue," Veloso's "13 de Mayo," Serge Gainsbourg's "Les Feuilles Mortes," and Björk's "Anchor Song" emerge from Afro-Peruvian rhythm and percussion, but the song choices speak for themselves. The spontaneity of live recording brings out all the warmth and folksiness in Baca's voice; she's surprisingly playful, given the unique circumstances. Recorded in downtown Manhattan during the fateful week of September 11th, Espíritu Vivo captures musicians doing what they do best: offering solace, escape, and expression through beauty and harmony. The elegiac "Toro Mata," made famous by Celia Cruz, is transformed into a confessional as Baca intones "I'll kill no more," over Ribot's atmospheric guitar and sizzling percussion. As all-encompassing as the tragedy was in those first few days, Baca and company manage to gloriously sail through the hurt and confusion to a place of light and love. It's the same instinct that has guided the music of Peru's uprooted, persecuted, and overlooked black population -- even as Susana Baca reaches a new plateau with Espíritu Vivo, her roots are deeper still.
