Ever since the birth of the music video format, some of the artists who have best used it to their advantage are underground hip-hop groups and MCs. Band videos, for many years, hinged mostly on showing the band playing their instruments. But in hard core rap, there are no instruments, and usually just a couple members. So hip-hop videos have been some of the more creative by necessity. Here are four of the best hard core rap and underground hip-hop videos of the past few years. Cage - "I Never Knew You"New York-area MC Cage started out as a relatively straightforward hard core rap artist in the underground hip-hop scene. But as the years went on, his sound matured past hard core rap into something much moodier and more experimental in genre. As his music turned darker, so did his hip-hop videos, like this one, which depicts Cage as a young boy stalking the ghost of a woman down abandoned city streets. Oddly, this video was directed by Shia LaBoeuf, a close friend of Cage's. Necro - "Die"Necro was a longtime associate of Cage's on the underground scene, but he stuck to a more hard core rap sound over time, especially one influenced by horrorcore. Case in point, his recent videos like this one for "Die," which includes creepy animated drawings and a woman made to look like a Mexican sugar skull. Twiztid - "We Don't Die"Detroit-area duo Twiztid are among the proteges of hard core rap duo Insane Clown Posse, specializing in a brand of underground hip-hop known as horrorcore. As such, their hip-hop videos are full of creepy imagery. This one includes Ouija boards and a few scenes set in graveyards and a hearse. Insane Clown Posse - "Halls of Illusions"This video by the notorious hard core rap group Insane Clown Posse comes from one of its most infamous albums, The Great Milenko. As one of its earliest wide-played videos, this is also one of its most memorable. It illustrates the mythology started in the underground hip-hop icons so-called "Dark Carnival" series of concept albums. The Dark Carnival, like the video shows, is a place where souls are judged in a series of scary attractions. Interestingly, for all the aggressive and menacing tone of this video, the bad guys lose in the end, as ICP follows them through a series of torments they suffer as punishment for things like domestic abuse.
