The Trio Madeira Brasil, a choro band from Rio, introduces us to fantastic renditions of a musical genre often considered the 'jazz' of Brazil. Brasileirinho isn't a film about the history of choro, but rather a journey with those who bring the music to life each day, with a subtle mélange of classical refinement and improvisation, during 'rodas de choro' held in squares, in the streets, at theatres, in suburban schools and at grafieiras, popular bars in the La Lapa district. With great feeling, this film lifts the veil from the fraternal ties between the musicians, the singers and their audience.
