There's a really interesting interview with British DJ Gilles Peterson on the September 17 2004 edition of the BBC radio program The World. He's put together a two-disc compilation of his favorite Brazilian music, one disc of oldies and one of new dance music. Lots of audio clips of tracks I'd never heard before, and some interesting perspective, including this (delivered from the vantage point of a highly-paid purveyor of dance music for bored Europeans):
"I just think in Brazil there's obviously as much pain as there is anywhere else in the world, and I think that when there's pain there has to be room to smile. And I think that's usually in places that have a lot of unhappiness that you get some incredibly uplifiting and beautiful poignant music from the heart which has suffered but can make you smile at the end of it."
