With their home becoming a hippie commune, the members of Os Novos Baianos live in a perpetual haze of marijuana smoke. Three times they had taken a shot at recording their second album --something electric, something mutant, something inspired by Jimi Hendrix. Three times it had fallen apart.
And then one night...
Band members assume it's the police.
But instead it's...
Gilberto jams all night with the band and returns the next night for more jamming.
He becomes their mentor.
Gilberto convinces the band to take the bossa nova lessons he's given them and try recording that second album again.
By the way, this story is a gross simplification of an article I found on the Sounds And Colours website
