Denver music fans packed the city’s streets and music venues despite a record-breaking heat wave to support Colorado musicians as two festivals featuring hundreds of local artists transformed neighborhoods into dance parties.

Blucifer’s First Rodeo, a new four-day festival organized by local artists, made its debut on South Broadway, while the Underground Music Showcase returned in a new home at the River North Art District. Together, the festivals brought more than 400 Colorado performers to venues throughout Denver.

Despite temperatures climbing past 100 degrees and setting daily heat records over the weekend, thousands of fans packed outdoor stages, neighborhood house shows and local venues to celebrate Denver’s independent music scene.

Blucifer’s First Rodeo emerged as a grassroots, artist-run celebration to replace the Underground Music Showcase on South Broadway after it relocated to RiNo this year.

Blucifer’s First Rodeo featured 260 Colorado bands and performers across nearly 40 South Broadway venues. A free Blucifer’s First Art Market drew visitors to Broadway, while roughly 20 private residences in the Baker neighborhood hosted independently operated house shows.

Organizers said the festival was created by musicians, photographers, poets and other artists committed to supporting Colorado’s creative community.

“100% of all profits going to paying 260 artists from all over Colorado,” organizers told The Denver Gazette.

The festival sold out during its inaugural run, with organizers estimating attendance surpassed 3,000 people. Performers included local acts such as Cheap Perfume, Wheelchair Sports Camp, Colfax Speed Queen and Los Mocochetes.

This weekend also saw the return of the Underground Music Showcase following an uncertain future for Denver’s longest-running independent music festival.

After last year’s festival, organizers warned there was not enough funding to sustain the event’s approximately $1.4 million operating budget.

The RiNo Art District Business Improvement District stepped in earlier this year and acquired a 50% ownership stake in the festival and committed $250,000 in annual funding for at least the next three years. The partnership secured the festival’s future and prompted its move from South Broadway to RiNo.

More than 160 Colorado artists were featured alongside national acts such as 54 Ultra, slenderbodies, Goldie Boutilier, Kaash Paige, Charlotte Sands, Twin Shadow and BAD NERVES.

The festival hosted two main outdoor stages along Larimer Street and more than a dozen other venues hosted performances in the area.

Festival Director Keanan Stoner said the move to RiNo reinforced the event’s mission of helping audiences discover new music and venues.

“UMS has always been about discovery,” Stoner said in a news release. “This partnership allows us to deepen that idea, helping people discover new music, new venues and new ways to experience Denver.”

Organizers estimated attendance exceeded 10,000 people per day as crowds filled venues and outdoor stages throughout the arts district.
