Run The Jewels is Killer Mike and El-P and it's totally worth listening to (all of their stuff), I know it's not a game but it's RTJ and I figured it's worth a post.
If you want to donate it goes to "National Lawyers Guild: Mass Defense Fund" but a donation isn't required and you can just grab the album for free.
