The NAMM Show: A four-day music trade show extravaganza at the Anaheim Convention Center. It's exclusive, closed to the public, one of the largest shows to ever roll through the convention center and a destination for music geeks, buyers and rockstars alike. This year's show took place on 1/14-1/17. Look for cameos from Slash, Danny Carey, booth babes, Bootsy Collins, Dave Mustaine, Lemmy and more. All photos by Andrew Youssef.
