From their website:

The Afro-Zebrabeat Amazon Orchestra mixtures and adds effects to the sound of guitarradas from Pará Sate with the percussive rhythm of Afrobeat.

Based on an experimental mixture, Amazon Zebrabeat African Orchestra redimension the traditional music from Pará such as carimbó and guitarrada, which receives strong influences of Caribbean music, hybridizing it to Afrobeat.
The result is a percussive instrumental musicality of easy enjoyment anywhere in the world, but that does not lose its regional roots music, both Amazonian and African.
