Celebrating the Ethiopian New Year with Mahmoud Ahmed

When Mahmoud Ahmed opens his mouth to sing, his voice trembles. This isn't some stylish affectation and it certainly isn't stage fright. That lovely wobble you're hearing is one of Ethiopia's brightest and longest-burning stars attempting to wrangle an entire spectrum of human emotion into his vowels. It's the sound of a national hero who, at 74, still sounds as stately as he does emotive.
