It is hard to imagine Africans would record and release an album of music with the name White African Power. But that is the title of an album released this month by the Tanzanian Albinism Collective, a group of amateur musicians from Africa who have albinism — a rare genetic condition that results in a lack of pigment in skin, hair or eyes. [...] White African Power is the newest in a string of projects produced by Brennan that seek to give voice to people who are normally voiceless.
