Query: Brazilian acoustic alchemy

Imagine a musician having a live acoustic album hit the Top Ten in the Billboard charts,being announced as #1 on America's Top Forty by Ryan Seacrest. That's how Chico Cesar catapulted to fame in Brazil. His intimate live acoustic concert album brought him out of obscurity into Brazil's popular consciousness.Chico Cesar's "Aos Vivos" offers the live acoustic versions of "Mama Africa" and "A Primeira Vista." It's not a wild rock concert,instead,it's Brazilian folk music,played on a few acoustic guitars (Chico collaborates with the popular guitarist Lenine on a few songs) "Tambores" is as percussive as the tambourines Chico sings about. "A Prosa Impurpura do Caico" sounds Hawaiian,as if it were played on ukeleles. "Saharienne" evokes Spanish flamenco. The audience sings along with "Mulher eu sei." "Templo" is quiet and reverential.This is perfect for adding to a Brazilian collection,and a great introduction to Brazilian folk music!
