Cassandra Wilson is an extremely versatile jazz diva who has aimed to revive the soulful tradition of Billie Holliday and Nina Simone. Her solo career as a Blue Note artist has seen her relentlessly exploring the roots of jazz, her most recent album ‘Travelling Miles’ being a critically-acclaimed tribute to Miles Davis. Cesaria Evora started life as a domestic servant in the former West African former Portuguese Colony of Cabo Verde, and she still performs barefooted. Her celestial, fado-inflected melancholy ballads have entranced audiences around the world. If the chemistry is there, this collaboration could be memorable.
