It is a documentary directed by the band Serpente, one of the oldest rock'n roll bands in Belo Horizonte. The band Serpente was formed in 1982 with an original objective for the time: to play live songs of their own authorship in a style based on the deepest roots of rock'n roll and traditional rhythm and blues.
Unfortunately the movie 20 Anos na Estrada do Rock is not yet available on Disney Plus.
