Searching around online I found a few frevo pics from various Carnivals in Recife. Enjoy.
(It seems someone else put together a lot of the same photos into a frevo video featuring a song from the 1940s. If you want to hear the kind of music the people in the photos below were probably dancing to, check out this song. Although, someone who left a comment on my post says the music linked to and the photos below wouldn’t naturally match up due to there being different styles of frevo.)
