The Chicago group Kids These Days is a hip hop outfit that includes tons of live instruments in their sound, something that hip hop needs more of. The last time we heard from these group they did their own version of "Flashing Lights." This time they return with a much darker and heavy song called "Don't Harsh My Mellow." The song starts off pretty grim, but an explosion of instruments quickly pops up and gets the energy level to the max. Check out the mass chaos in the video.
