Morgan Wallen is setting a new attendance record at Nashville's Bridgestone Arena.
During a free acoustic concert on Friday night, around 19,300 fans flooded the venue. Wallen announced the pop-up concert a day beforehand -- in support of the release of his brand-new, third studio album, 'One Thing At A Time.'
Over a million fans from around the world also livestreamed the event. Wallen calls it "a night that I will never forget."
