I usually don't mention photographers collective on this blog, but I found that ArcaPress (started in May of 2010) which highlights Brazilian culture and covering such areas as religion, indigenous people, economic issues, urban reality, environment and wildlife.
I was particularly drawn to Between Faith And Fever by Guy Veloso, and Maracatu by Celso Oliviera.
Maracatu is the name of performance genres found in northeastern Brazil and in its northeastern state of CearĂ¡. Maracatu describes the music style that accompanies these performances. Maracatu has close ties to Afro-Brazilian religious ceremonies, and these performances are secular manifestations of these cults.
