— DENVER, COLORADO — The most common of fixtures captures the attention of a small boy in fluorescent orange shorts, a stylish hipster couple holding hands, a baby boomer pair with cameras. They bend over to listen. They stomp their feet. They pass over or stand on one of the most common objects on any city sidewalk – the grate.
Downtown Denver has public art that’s hiding in plain sight. In a city teeming with street art, Soundwalk is easily overlooked. Six stainless steel grates spaced 50 feet apart, make unexpected sounds as you step on them. A yodeling woman, clucking chicken, huffing gorilla, subway car, gurgling water, fog horn, crashing waves – over 100 sounds. The sound comes from speakers under the grates. Tape recorders in a nearby building play the sounds when activated by motion detectors.
“My children call it silly street.” says local resident, Debbie.
The day I went to Soundwalk I was accompanied by two pals. We had lots of laughs but had the most fun pointing it out to others. Watching people discover and react is part of the fun. Some are completely fascinated, some perplexed, others oblivious.
Jim Green, the sound artist, uses sound in unexpected places to surprise and delight passersby. Jim has installed sound art in other Denver locations including the Denver airport train, Convention Center, Art Museum, and construction site fences. In other cities, he has installed talking drinking fountains, musical warning lights, amplified floors, and vestibules.

Artist Statement
“I have used sound as my primary medium for thirty years and since 1984, focused on site-integrated work in public. The intent is to playfully integrate unexpected sound into existing environment. I am drawn to common environments and find them successful sites for my playful style of public art. My people-oriented approach uses sound to engage the public with humor and surprise to produce a social, interactive experience. I believe public art functions best when it humanizes public space. I also have extensive design team experience which includes teamwork with other artists, architects, engineers, contractors, administrators, and community.”
— Jim Green
Located on the NW side of the 1500 block of Curtis, it is between 15th and 16th. Soundwalk is always open, always free, and appeals to people of all ages.
TIP– Ask others what they know about the sounds.
It’s a fun art experience, so get out & GO
Thanks for stopping by, MaryGo
Great article, Mary. It was a fun side trip that day. Thanks for researching Denver Art and for leading us to laughter at lunchtime! Patty
It was my pleasure Patty. What fun, even though we could have easily missed it. Denver is a great city full of amazing art.
What a fun idea! Thanks for sharing.
Love it! Leave it to YOU to find something like this!
That is such a unique idea! I love street art and I think sound art is an entirely different concept that I’ve never even heard of! It sounds like you had a wonderful tour.
Had a blast. Denver has several installations by the same artist. –MaryGo
Never heard of a sound artist and never heard of Jm Green — but give me Jim Green over Damien Hurst anyday. What a great idea!
This sounds like a whole lot of fun! Hope it’s still around on my next trip there in the spring!
I’m sure it will be. It’s a hoot. Especially watching the unaware.
Always go for art with a sense of humor… and soundscapes can be so interesting. Thanks for telling us about it.
Yes, I like soundscapes also. Sometimes they can startle me, but I still like them.
