Oskar Blues Brewery brings back its annual blend of Fresh Beer, All-Day Music, local flavor, & unmistakably Colorado vibes.

Every spring, as the Front Range tries to shake off the last of winter, one event reliably pops up to remind Longmont exactly what this season is supposed to feel like: sunshine, live music, and a fresh Oskar Blues beer in hand. On April 18, Dank Grass Festival returns to Oskar Blues Brewery—a full day dedicated to IPAs and bluegrass music, offered with the classic Oskar Blues attitude that’s fueled Colorado culture for decades. Running from noon to 8 p.m. at 1640 South Sunset Street, the festival blends Colorado’s two most reliable warm–weather ingredients: live music and craft beer. And with the date landing conveniently close to a certain culturally significant moment in Colorado’s late–April calendar, the timing feels particularly fitting.

Dank Grass Festival remains one of the rare all–day gatherings where everything feels easy. Free entry means you can roll in, settle anywhere you like, and let the music guide the day. The brewery grounds transform into a spring hangout zone where bands rotate across the stage, glasses stay full, and the entire place pulses with the relaxed energy that defines Longmont’s creative community. This year’s lineup brings in a mix of nationally touring and regionally rooted talent ready to fill eight hours with high–energy, foot–moving sound. Sicard Hollow brings progressive bluegrass with amplified intensity. Pert Near Sandstone contributes their signature harmonies and fast–flying instrumentation. Armchair Boogie adds jam–infused grooves, while The Last Wild Buffalo starts out the day with rich, atmospheric Americana. Together, they create a musical arc built for spring—uplifting, warm, and impossible to stand still through. At the center of it all is Oskar Blues, keeping the taps flowing with IPAs that lean into the “dank” part of Dank Grass. Expect everything from classic hop-forward staples to limited releases brewed specifically for the festival. Crisp, hazy, resinous, or citrus-packed—whatever version of IPA fits your personal preference, you’ll
find it here. It’s the kind of beer lineup that makes an April afternoon feel like a stretch of summer before summer even shows up.

Food trucks will be serving across the grounds, offering everything from handheld cravings to heartier festival fare. Whether you’re diving into comfort food or choosing something lighter between sets, every option is designed to complement a pint and keep you fueled as the day rolls on.

What makes Dank Grass unique isn’t just the music or the beer—it’s the atmosphere. There’s a distinct Colorado rhythm to the way people move between quieter pockets of chilling on the taproom deck, bursts of dancing near the stage, and casual conversations with a fresh beer in hand. It’s easygoing, unhurried, and rooted in that shared understanding that spring in Colorado deserves to be enjoyed outdoors with friends, great music and a whole lot of good beer.

So, when April 18 rolls around, head to Oskar Blues Brewery in Longmont. Bring your friends, your appetite, and your appreciation for finely tuned strings and finely crafted IPAs. Dank Grass Festival is ready to welcome you—no ticket required.
