Heavy Metal Kings is a group featuring veteran rappers Ill Bill and Vinnie Paz. In 2006, Ill Bill was featured on the single "Heavy Metal Kings" by hip hop duo Jedi Mind Tricks, released through Babygrande Records. The single was released in a limited edition blue vinyl pressing, with every copy signed by group vocalist Vinnie Paz. "Heavy Metal Kings" is the lead single from the group's fifth album, Servants in Heaven, Kings in Hell. The song features a sample from "Boiling Rage" by German composer Carl Orff, taken from his famous cantata Carmina Burana, and a vocal sample from "Front Lines" by Mobb Deep for the chorus. The song's music video was released shortly before the album's release, and featured guest appearances from the group's DJ, DJ Kwestion, and R.A. The Rugged Man.
Ill Bill and Vinnie Paz have since combined forces to form a group of the same name, "Heavy Metal Kings," and record a full self-titled album to be released April 5, 2011 through Enemy Soil/Uncle Howie. "Keeper Of The Seven Keys" produced by up and coming producer, C-Lance, is the first track from the new Heavy Metal Kings album. The album features production from DJ Muggs, Ill Bill, Shuko, Sicknature, C-Lance, Grand Finale, Jack of All Trades, Junior Makhno, Vherbal, and DJ Premier protégé Gemcrates alongside a cast of emcees, including Reef the Lost Cauze, Slaine, Crypt the Warchild, Q-Unique, and Sabac Red.
