Here’s what’s up for Saturday, September 18th – the final day of Summerfest, the World’s Largest Music Festival!

It’s swan song time – Summerfest 2021 is hitting its final day of the season, as this year the “World’s Largest Music Festival” has been running Thursdays through Saturdays over three weekends in September, with each weekend kicking off with a Wednesday concert at the newly-remodeled American Family Insurance Amphitheater.
Speaking of, Summerfest is requiring proof of COVID vaccination or a negative test within the previous 72 hours of entry, so be sure to bring that as you go. Masks are recommended for indoor activity (restrooms, for example), but not required. Grounds are open from noon until midnight, per usual.
So, it’s Summerfest DAY 9: Saturday, September 18th. And here’s the full info and lineup of performers for today and tonight!
