Filmmaker and Congolese music scholar Alan Braine explains.

The Congolese have a word, it's called sevene.

The sevene is that moment where the orchestra really explodes musically and everybody gets to dance.

I believe that's the moment where the Congolese saw this kind of epic version of salsa that they hadn't necessarily seen before or been exposed to in a massive way.

Um, and it had effects on them.

This is filmmaker Alan Brain.

Viva la musica.
