Welcome to the Arab Sing. As upheaval has transformed the region in recent years, modern music has emerged to channel the complex emotions of the Middle East — with new technology making it more accessible than ever. Streaming services are taking off, and traditional Arab music has been joined by everything from heavy metal to hip-hop. Doha, Dubai and Abu Dhabi boast music halls and a festival scene is emerging. Though the number of listeners is tiny compared to the U.S., these voices are finding new ways to be heard.
