Not only had I heard of MGK, but he's been my favorite rapper who's gonna die young for years.
He's a complete fuck-up. This is who he is, from a Rolling Stone article:
Thanks to a perilous combination of bad luck, fearlessness and serious partying, he keeps getting hurt. Last year, he was wasted in Denmark when he tried to imitate a sport he’d just seen on TV (“What’s the thing where they hop over the fences and shit? Hurdling?”). “Do you guys wanna see some real Olympics?” he asked his friends, climbing on a car. He didn’t realize it had rained. “My foot slides down the entire front windshield … and I fucking face-plant right on the concrete.” He needed facial stitches and a cast on one arm, but still played his next show.
