One of Africa's greatest singers, Angélique Kidjo, has been added to the already star-studded line-up of EFG London Jazz Festival's opening gala Jazz Voice.

Angélique has enjoyed an illustrious career across the globe spanning many genres, from Afrobeat to gospel, jazz, Latin, reggae and beyond.

Also joining the Jazz Voice vocal ranks is Mads Mathias - known in his native Denmark for his charismatic performances and spirited personality.

They add to an already impressive line-up, featuring Seal, Liane Carroll, Mica Paris, Miles Mosley, Tony Momrelle and Vanessa Haynes, all accompanied by Guy Barker's 42-piece orchestra and host Jumoké Fashola, to bring in this year's festival with a bang.
