Korn's Brian "Head" Welch is back at work. The guitarist rejoined the band this weekend at Rockfest in Kansas City, Missouri for his first concert since being sidelined last month with kidney stones.
Welch was forced to leave Korn's tour of Russia, and underwent surgery there to help fix the issue. He returned to the U.S. last week for more treatment, and was unsure when he'd be able to take the stage again. But Welch said he was pain-free on Friday, and thanked the fans for welcoming him back on Saturday at a "crazy" Rockfest gig.
