Eastern DRC has long been wrought by armed conflicts, killing and displacing hundreds of thousands since the late 1990s. Why? Congolese singer Mista Poa points to ethnicity, suggesting it's caused even more bloodshed than disagreements over mineral wealth. In this week's video edition of My Song, Mista Poa talks about 'Jembe'. The track takes its name from a Kiswahili word for 'hoe', which he sees as a meaningful symbol for cooperation. Mista Poa's hope is that Congolese people from many ethnic backgrounds unite, like farmers working a single field, to make the DRC a better place for the next generation. My Song showcases the personal stories behind the songs of Africa's most compelling musicians. You'll hear these musicians in their own words. No presenter, no interviewer - nothing to get in the way. Just African voices on African music.
