From this Kizomba site:
Kizomba music was born in Angola (in Luanda) in the 80’s following the
influences of traditional Semba music (the predecessor of Samba from
Brazil) and Zouk music from the groupe Kassav from the French
Caribbean Island Guadeloupe. On this basis, Kizomba music emerged as a
more modern music genre with a sensual touch mixed with African
rhythm. Unlike Semba, Kizomba music is characterised by a slower and
usually very romantic rhythm. Given that Angola is a former Portuguese
colony, Portuguese is the principal language spoken in Angola and
thus, also most Kizomba songs are sung in Portuguese. However, Kizomba
songs of the very beginning were song in Kimbundu and in other
National languages of Angola. Famous Angolan Kizomba singers include
Bonga (Semba, traditional music), André Mingas (traditional music),
Liceu Vieira Dias, Neide Van-Dúnem (Semba, tradional music), Don Kikas
(Semba, Kizomba), Calo Pascoal (Kizomba), Heavy C. (Semba, Kizomba),
Puto Portugues (Semba), Maya Cool (Kizomba, Semba), Matias Damasio
(Kizomba, Semba), Rei Helder (Semba), and Irmãos Verdades (Kizomba).
