CRS is a crazy cool week for Country Radio because it's a bunch of seminars and industry events - but it also means that basically every country musician is in Nashvile and awesome stuff like this happens. Jason Aldean was performing at a showcase when none other than Garth Brooks stepped on stage to sing "Friends in Low Places" with him.
That wasn't his only stop for the night...he ended up at one of the Honkytonks on Broadway and surprised the crowd there, too!
