I had heard the Metallica concert sold out when they opened US Bank stadium (2016), I was curious what attendance was for that concert.
Looks like they sold out at 50,000 for that show. So 50,000 fans in a 67,000 seat venue (This tour they played at the basketball arena, Target Center).
Alerus had 19,000 in a 13,000 seat venue.
Metallica will be playing in the 15,000 hockey rink in Saskatoon this coming Saturday, where Garth Brooks holds the attendance record there in 2016 with 15,800 fans.
