From their press release:
"José Eduardo dos Santos has ruled the southwestern African country of Angola with an iron fist for more than three decades. He installed his family as owners of the country’s major businesses, and ordered the routine harassment, arrest, and execution of politicians, journalists, activists, and students who oppose the government and expose its corruption."
Why do so many pop stars perform for dictatorships? Are they that hard up for money? Do they not have a manager or agent to vet this shit?
