The Castle Rock Summer Concert Series turns 10: the full 2026 lineup, prices, and the free series people forget exists.

The Castle Rock Summer Concert Series hits its 10th anniversary in 2026, and the Town has the full lineup posted. There are two things worth getting straight up front, because they get conflated constantly: the headline Summer Concert Series is entirely ticketed, and there is a separate, free monthly concert series that runs on a different night. Both happen at the Amphitheater at Philip S. Miller Park. Here is the whole picture, by use case.

The ticketed Summer Concert Series, five shows, June 26 to August 29:

• Friday, June 26: The Marshall Tucker Band, with special guest Ben Chapman. The Marshall Tucker Band is a fitting 10th-anniversary opener; they played the inaugural 2016 season and are coming back to mark the decade.
• Saturday, July 18: Jackson Dean, with special guest Tigirlily Gold. The country bill and the one most likely to fill the lawn early.
• Saturday, August 1: Fitz and The Tantrums, with special guests Sun Room. This is the Colorado Day show, programmed around the America 250 and Colorado 150 celebration.
• Saturday, August 15: Cheap Trick, with special guests Pat Travers Band. The legacy-rock night.
• Saturday, August 29: Still the Same, A Bob Seger Tribute with the Denver Pops Orchestra. The orchestral closer, and the one show that runs about an hour later than the others.

Prices and tickets. Tickets went on sale to the general public on April 10, 2026 through TicketWeb, so they are available now (the town-resident presale ran back in late January). A Season Pass covering all five national acts is $150 plus applicable fees and went on sale February 4, ahead of the lineup announcement, as a loyalty discount; it comes as a physical lanyard pass ready by June. Individual ticket prices vary by show and seating area (general-admission lawn, tiered orchestra seating, and elevated patio boxes with cocktail service). The only show with publicly posted per-ticket numbers is the August 1 Fitz and The Tantrums Colorado Day show: $45 general admission, $65 orchestra, $80 box. For the other four, the Town lists prices as varying by performance, so check the official Concerts page for the show you want.

Timing. Gates are generally 6 p.m., the opener around 7 p.m., and the headliner around 8:30 p.m. The August 29 Denver Pops closer runs roughly an hour later than that pattern. The lawn fills earliest for the country bill (Jackson Dean, July 18); arrive early if you want a spot in the closer rings rather than the back third where you watch the screens.

The free series almost nobody plans for. Separate from the ticketed lineup, the Town runs a free monthly concert series at the same amphitheater, Tunes for Trails and Perks for Parks, on the third Thursday of each month. Gates open 5:30 p.m., music runs 6:30 to 9 p.m., open seating, with donations benefiting the Castle Rock Parks and Trails Foundation. The 2026 free dates: June 18, The Rick Lewis Project; July 16, That Eighties Band; August 20, Santa Rios; September 17, Ninety Percent 90s. If you have a flexible budget and a Thursday free, this is the locals' move and it costs nothing.

One correction worth stating plainly, because we have seen it repeated and we want this page to be the accurate one: there is no free Wednesday concert series in Castle Rock. The free series is on Thursdays (Tunes for Trails), and the Wednesday-night summer concerts people sometimes describe do not exist in the Town's 2026 programming. If you want free, plan around the third Thursday.
