It is always a delight when The African Children's Choir visits the studio. Music for Life, its parent organization, works in four African countries: Uganda, Kenya, Rwanda and South Africa. The choir of 7- to 10-year-olds performs worldwide, including before presidents and heads of state, and alongside prominent artists like Paul McCartney and Mariah Carey. The African Children's Choir has four more performances in Spokane this week, including Thursday at 7 p.m. at St. Aloysius Church.
