Samba bands originated in Brazil in the early 20th century. They were initially formed by African slaves and their descendants as a way to express their culture and heritage. Samba bands quickly became popular throughout Brazil, and they are now considered an essential part of Brazilian music.
Samba bands are typically associated with carnival celebrations, but they can also be found performing at other events, such as concerts, festivals, and parades. Samba bands have also become popular in other parts of the world, and they can be found in many cities around the globe.
