Music for your Midweek: Chico Buarque

This song has always been haunting to me.

I did a bit of research, and this is what I found (from wikipedia): 

"During the Brazilian military coup of 1964, Buarque wrote about the events which transpired and avoided censorship by using cryptic analogies and wordplay. For example, in the song "Cálice" ("Chalice", or Jesus' Last Supper "Cup"), a duet written with Gilberto Giland performed with Milton Nascimento, he takes advantage of the homophony between the Portuguese imperative "shut your mouth" --cale-se-- and "chalice" --cálice-- to protest censorship against freedom of speech by the dictatorship, disguised as the Gospel narrative of Jesus' Gethsemane prayer to the Father to pass from Him the chalice of bloody death probation. The line "I wanna sniff diesel fume" is a reference to the death of political prisoner Stuart Angel, who had his mouth glued to a jeep's exhaust pipe during a torture session."

wow wow wow
