3OH!3 are a Boulder duo who turned cheeky, synth-heavy pop-rap into chart hooks with DIY grit and a wink.

From Boulder basements to blog-pop big rooms

This anniversary set zeroes in on the Streets of Gold era, likely leaning into glossy beats and talk-sung verses that bounce. Expect anchors like My First Kiss, Double Vision, Touchin on My, and a late-set Don't Trust Me for the big group shout.

Hooky chaos, tightened for live rooms

The crowd skews mixed-age, from day-one Colorado followers to newer pop fans, with friend groups trading hooks rather than crowd-surfing. Trivia: the name 3OH!3 nods to the 303 area code, and they have hosted a March 3 community day in Colorado to raise funds. They also notched early writing and production credits with Kesha, while a single version of Starstrukk featured Katy Perry. Note: these setlist and production guesses are educated predictions, not confirmed details.

Neon Nights: The World Around 3OH!3

Expect neon accents, mesh caps, metallic windbreakers, and throwback tees that nod to early 2010 playlists.

2010 glow, updated for now

People volley the shush-girl line during Don't Trust Me, and you will see the 303 hand sign flash when the kick drops. Merch trends toward bold varsity fonts, reflective inks, and cheeky one-liners pulled from Streets of Gold. Pre-show chatter is half memory lane and half curiosity about deeper cuts like I Can Do Anything and House Party getting air again.

Group-sings and in-jokes that welcome newcomers

Friend groups post up in loose clusters so everyone can jump on the big hooks without shoulder-checks. It reads like a reunion built for motion, with space for first-timers to learn the chants in real time.

Beats, Hooks, and How 3OH!3 Make It Pop

Vocally, 3OH!3 work as a tag-team, tossing lines back and forth so hooks hit like chants.

Two voices, one giant hook

Arrangements favor short verses, bold pre-choruses, and extended post-chorus chants that leave room for claps and hand signs. Live, the synths and 808 kicks sit heavy, but tempos breathe, often cruising near club pace before dropping to halftime for impact. Guitars stay sparse as percussive color, while keys drive the leads and a pad rig fires samples to keep transitions tight. A neat quirk is how second choruses often switch to a rougher shout blend, then the beat cuts for a bar so the crowd finishes the line. Another tweak you may notice is some hooks drop a key step or simplify the melody to keep singalongs big without strain.

Lights that punch, not distract

Visuals lean on bold color blocks and strobe hits on the downbeat, supporting rhythm first and leaving space for the jokes to land.

Familiar Sparks Near 3OH!3

If you ride for Kesha, you will catch the same glittered synths and brat-pop bite that 3OH!3 helped shape.

Kindred mischief-makers

Fans of Cobra Starship line up with the snarky hooks, talk-sung cadences, and punchy four-on-the-floor grooves. Followers of Breathe Carolina, especially from the Warped-to-EDM years, will find familiar drops and chant breaks.

Where synth-pop slaps hands with shout-rap

Party-rap devotees of LMFAO will hear overlap in bass-first choruses, though 3OH!3 keep a leaner duo dynamic and drier punchlines. If you like shows where the crowd becomes part of the rhythm through claps and call-backs, this sits in the same lane. The throughline is bright synth leads over simple, stomping drums, plus humor that invites a sing-and-smile response.
