Alton Amphitheater Announces Free Pop-Up
Concert Series with Live Music, Local Food
ALTON, Ill. – This September, the Alton Amphitheater is inviting the community to slow down, gather with friends and family, and enjoy three Friday evenings filled with live music, local food and unparalleled sunsets over the Mississippi River.
The 2026 Pop-Up Concert Series will take place Friday, September 4, September 11 and September 25 from 6-9 p.m., offering a relaxed atmosphere with regional live music, food vendors, yard games and plenty of room to spread out along Alton’s scenic riverfront. Admission is free.
Created as a pilot program for the 2026 season, the series is designed to bring more people to the amphitheater outside of major festivals while exploring new ways to activate the space and expand community programming.
“The amphitheater is one of Alton’s greatest public gathering places, and we want to activate it beyond our signature events,” said Abby Haynes, Chair of the Alton Amphitheater Commission. “The 2026 Pop-Up Concert Series is an opportunity to experiment with a different style of programming, encourage more people to enjoy the riverfront, and learn what resonates with our community as we continue growing the amphitheater’s event calendar in the years ahead.”
Friday, September 25 – Borderline – Country
Borderline closes the series with one of the St. Louis metro area’s premier country music experiences. Performing throughout the region for more than 20 years, the band has built a social media following of more than 17,000 fans and is known for its strong live shows and broad regional appeal.
