This is a unique opportunity to look into a rehearsal of thrash metal greats, Arizona's Sacred Reich. Uploaded with permission, this is cell phone video that was taken from the jam space where Wiley, Jason, Greg, and Phil crush it out in a way that only they can do. Sharing this as a fan with all the metal-heads out there, I can tell you that these dudes are some of the finest gentlemen I have had the pleasure of meeting. Hope you enjoy, the sound isn't the greatest, but the experience is very cool.
