Eminem has once again dropped a surprise album, releasing “Music to Be Murdered By” on Friday. The album dropped along with a video for the song called “Darkness” which calls for changes to America’s gun laws. The Detroit rapper’s new music video depicts a shooting at a concert. The lyrics and storyline of the video specifically allude to the 2017 mass shooting at a music festival in Las Vegas that left 58 people dead, making it the deadliest mass shooting in modern U.S. history. It closes with audio and video footage of news broadcasts from other recent mass shooting around the U.S. and an appeal to register to vote. “Music to Be Murdered By” is Eminem’s 11th studio album, according to his website. Among many collaborators, the album features Ed Sheeran, Skylar Grey, Anderson .Paak and Juice WRLD, the 21-year-old rapper who died in December.
