This week, a musical nod to a man who played an important role in Brazil's Tropicalismo movement. Caetano Veloso is a musician, composer, and political activist who along with Gilberto Gil, Os Mutantes and a handful of other Brazilian artists took  Brazilian pop, bossa nova and African music and fused it with rock and roll and avant-garde music in the late 1960s.

It was the musical component of the Tropicalismo movement which was highly influenced by poesia concreta or concrete poetry; an avant garde expression from the 1950s.

Veloso's music was targeted by the then right wing military government and he was eventually arrested and exiled. His music ranges from sweet sounding bossa style of Joao Gilberto to Frank Zappa-esque compositions.

Plus, the sounds of The Devil's Anvil, a Greenwich Village group of mostly Arabic Americans who played a mix of Middle Eastern folk and fuzzed out guitar rock. They released only one album in 1967.
