The Ohio-based O'Keefe Music Foundation has a very specific and important mission to "enable children from around the world to record and film their musical performances for free." It's a great cause — especially since more than a few of those musical performances have been of the metallurgic variety. Having worked with nearly 1,000 students on 200-plus music videos, the organization's latest offering is awesome rendition of Pantera's "5 Minutes Alone," performed by a band of youngsters ranging in age from 13 to 17. Taking center stage in the clip is high-octane vocalist Kaden Karns, who previously fronted an equally badass take on the Cowboys From Hell's "I'm Broken." In addition to Pantera, O'Keefe kids have also covered Slayer ("Raining Blood") and Slipknot ("The Devil in I") in the past. Watch their rendition of "5 Minutes Alone" above.
