Post Malone was in attendance for Iron Maiden's Rock in Rio Festival set and seemed to be hanging and taking photos with some of metal's biggest names.
Both Mike Portnoy (Drummer Dreamtheater/Sons Of Apollo) and Phil Demmel (Guitarist Echoes of Reckoning/Vio-lence) took the opportunity to snag and post photos to their Instagram accounts. Which you can see below.
