The members of Zimbabwean Afropop band Mokoomba grew up playing music in the tourist-friendly border town of Victoria Falls. But performing for locals and waterfall visitors from around the world encouraged the group to develop a songbook with a global perspective. Its sound is rooted in southern African rhythms, harmonies, and call-and-response vocals to which they have added aspects of Congolese soukous, hip-hop, and salsa. Mokoomba’s six members meld these genres seamlessly without sounding contrived. On the group’s most recent album, Rising Tide, opening cut “Njoka” spells out its modus operandi: It energetically starts with vocals derived from both speedy old-school rap and frog-voiced, Zulu mbaqanga styles before soulful lead refrains come in accompanied by high-pitched guitar and funky bass and keyboard grooves. The soulfulness comes courtesy of lead singer Mathias Muzaza, who warbles both in a traditional a cappella manner and a polished contemporary style, with the aid of his bandmates whose performances make both approaches work. Mokoomba performs at 7 p.m. at Hill Center at the Old Naval Hospital, 921 Pennsylvania Ave. SE. $12–$15. (202) 549-4172. hillcenterdc.org.
