Perhaps it is funaná’s earthy exuberance that caused it to be banned by Cape Verde’s colonial overlords. It’s the polar opposite of the Cape Verde’s better known morna ballads, popularized by the late Caesaria Evora. Morna is a close cousin of Portuguese fado, full of reflective regret. Funaná is up-tempo, propulsive, accordion and percussion-propelled dance music. At nearly 80, Bitori, aka Victor Tavares, survived the ban and decades of global obscurity to become the music’s foremost proponent.
