“Sounds of Pamoja” is Nyege Nyege Tapes’ latest foray into the world of Tanzanian Singeli, the breakneck dance strain that’s quickly moved from Dar es Salaam throughout the world. The music is fresh and unpredictable, switching beats every few bars and rattling through hyper-local dance styles with jagged, joyful ease. It’s breathtakingly unique dance music that recalls the youthful spirit of Detroit techno or footwork, with rapid body movement, social combustion and tongue-twisting lyrical one-upmanship guiding the rudder.
