They're incredibly talented, that's for sure. I've been listening to techno, various subgenres of electronic music for years and years and they have some of the most interesting use of samples I've ever heard. Sorry my english isn't the best

Death Grips IS a good band. The guys in the band ARE good.
The United States Marine Corps IS a title. Marines ARE individual soldiers. When you say, "The marines are going to blow you guys to kingdom come" you aren't talking about the marines as a title, you're talking about multiple marines.
