Chicago group Kids These Days is back with a gloriously dark and menacing video for their latest single, "Don't Harsh My Mellow." The track begins with menacing, dissonant piano, that is quickly overran by screaming guitar, rebellious vocals, and booming drums. Elements of hip-hop, rock, electronic, jazz, even classical can be heard throughout this track of less than four minutes. Truly some amazing stuff. Look out for their upcoming project Traphouse Rock.
