Staff Benda Bilili are like nothing you have ever seen or heard before. A group of paraplegic street musicians who live in and around the grounds of the zoo in Kinshasa, Congo, they make music of astonishing power and beauty. The band's mesmerising rumba-rooted grooves, overlaid with vibrant vocals, remind you at times of Cuban nonchalance, at other times of the Godfather of Soul himself. You can hear echoes of old-school rhythm and blues, then reggae, then no-holds barred fun
