Quick Info

Rhythm on the River is Longmont's signature summer event - a free outdoor concert series on Friday evenings along St. Vrain Creek. The community gathers with blankets and lawn chairs to enjoy live music, food vendors, and Colorado summer evenings. It's the kind of small-town event that makes Longmont feel like home.
The Music
The series books a variety of acts across genres:
- Rock and pop cover bands
- Country and Americana
- Blues and funk
- Regional touring acts
The focus is on accessible, crowd-pleasing music that appeals to a broad audience. Don't expect cutting-edge acts - this is family-friendly entertainment designed to bring the community together.
Check the city's website or local calendars for the current season lineup and schedule.
Attending
Bring:
- Blanket or lawn chairs
- Cooler with drinks (check alcohol policies)
- Cash for food vendors
- Layers - Colorado evenings cool down
Timing: Concerts typically start in early evening and run until dusk. Arrive early for better spots, especially for popular acts. The event runs rain or shine, though severe weather may cause cancellations.
Parking: Limited parking near the venue fills quickly. Street parking in surrounding neighborhoods or downtown with a short walk. Consider biking or walking via the St. Vrain Greenway.
Food & Drinks
Food trucks and vendors set up at the venue. Expect standard festival fare - tacos, burgers, barbecue, and treats. Prices are reasonable for event food.
Some people bring their own food and snacks. Check current policies on coolers and outside food/beverages, as rules may vary by year.
The downtown area is close enough for pre-concert dinner at a restaurant or post-concert drinks at a brewery.
For Families
Rhythm on the River is explicitly family-friendly:
- Kids can run and play on the lawn
- No rowdy concert atmosphere
- Ends at a reasonable hour
- Other families everywhere
The setting along the creek provides space for kids to explore while parents enjoy the music. Bring activities to keep little ones entertained during longer sets.
Tips
Arrive early: Good spots go fast, especially for popular acts. Arriving 30-60 minutes before music starts ensures a prime location.
Expect crowds: Popular summer Fridays draw significant attendance. Part of the fun is the community atmosphere, but if you want space, arrive early.
Weather check: Colorado summer evenings can bring afternoon thunderstorms. Check the forecast and have a backup plan. Events continue in light rain but severe weather cancels shows.
Make it an evening: Combine with dinner downtown, a brewery stop, or a walk on the greenway for a full Friday night out in Longmont.
