Many of the shops in the historic centre sell Olodum clothes and merchandise and you can't really avoid seeing the distinctive logo of the group when you're in the old town.
The group was set up in 1979 by the musician Neguinho do Samba with the aim of providing cultural activities for young people centered around music.
The group looks to celebrate Afro Brazilian culture, fight racism, and raise self esteem within the Afro Brazilian community.
It turns out that I had heard of Olodum as they were featured in the video of Micheal Jackson's They Don't Care about us.
