Present Box: Jonathan Mason, July 20 to July 24

Think of this installation as a work of artistic synesthesia. During the interactive sense-blending exhibition, Colorado artist Jonathan Mason pairs seven musical notes with seven different colors, so guests can choose a combination of hues to produce their own melodies. Up to seven viewers at a time can experiment with the shades to create their own harmonies on a glockenspiel. Tue-Sun 11 a.m.-5 p.m. Boulder Museum of Contemporary Art, 1750 13th St., 303-443-2122. Free.

Spirit of Colorado, July 21

Next time you visit the airport, avoid the TSA line and celebrate Colorado’s Western heritage at this lively festival instead. After you sip on whiskey from Old Town Distilling Co., visit ponies at a Colorado Horse Rescue’s petting zoo, try to spend eight seconds on a mechanical bull, or take silly selfies in a cowboy-themed photo booth. As you listen to live performances by folksy group Rocky Mtn. Bluegrass and singer Eric Lane, who plays covers of pop and rock hits, make sure to savor this worry-free time in DIA—it might never happen again. Thu 11 a.m.-8 p.m. Denver International Airport, 8500 Peña Blvd., 303-342-2000. Free.

What’s Your Everest?, July 22 to July 23

Everest. Proceeds benefit No Barriers, a nonprofit that creates opportunities for disabled individuals to participate in recreational activities. Fri 5-8:45 p.m.; Sat 5:45 a.m.-noon.

Tattoo Masquerade, July 22 to July 24

Inked Magazine named Denver the fifth most tattooed city in America, so it’s no surprise this massive body art–centric convention is coming to the Mile High City. For three days, festival attendees can peruse the works of tattoo artists from 22 states as well as the United Kingdom and enjoy dance performances from Darshan Dance and Ooh La La Burlesque. You’re not required to have a tattoo to attend—but if you have a piece you’d like to show off, you can enter into a tattoo competition to see if your body art is the best in town. Fri noon-10 p.m.; Sat 10 a.m.-10 p.m.; Sun 10 a.m.-8 p.m. Colorado Convention Center, 700 14th St., 720-203-9415. $30-$70.
