Vince Staples' Summertime '06 was one of the hardest projects of 2015 but the Long Beach, California rapper shouldn't be put in the "gangsta rap" box. On Flume's "Smoke and Retribution," Staples comes with his same methodical flow, but sheds the tough guy image to show a lovesick, downright sentimental side.

With bars like "You don't need nobody else/If it can't be that way, I'll just be all by myself" and "I like the way you stay away from me/You make melt," Vince doesn't sound like the same rapper who spit bars like "I ain't never ran from nothin' but the police."

The unlikely collaboration certainly caught the people by surprise and the comments on SoundCloud tell the story. "Holy Jesus...that's how you redefine a 'genre,'" writes one listener. Another writes, "Man, Flume and Vince Staples is a dream come true. A match made in heaven."

With over 400,000 streams on SoundCloud already, Flume and Staples have a potential smash on their hands.

Flume is an Australian producer and announced that his upcoming Skin album will drop in 2016. "Smoke and Retribution" is the followup to the first single, "Never Be Like You."

This isn't Vince's first foray into the EDM (or House, or whatever may have you) genre. In Aug. of 2015, the West Coast MC joined With You. for "Ghost."
