Milwaukee’s low-end underground just got louder. AyooLii, one of the city’s most restless and prolific voices, has linked up with Midwest trap firebrand Certified Trapper for a new single called “Carry and Conceal,” presented by Run Along Forever. If you’ve been waiting for a collab that pairs Milwaukee’s gritty, club-rattling energy with a hard-nosed trap swagger, this is the one you’re going to want to play twice.

Watch the official music video here:

AyooLii has spent the last few years carving out a lane in Milwaukee’s booming rap scene, earning co-signs from outlets like ROC Nation and WIRED for his short, high-energy tracks built on heavy bass, auto-tuned bite, and that frenetic DIY spirit the city has become known for. Tracks like “Shmackin Town” helped cement his reputation as a foundational voice in Milwaukee’s trap/low-end continuum, and “Carry and Conceal” continues that momentum without breaking stride.

Certified Trapper, meanwhile, brings exactly what his name promises. Coming off high-profile releases like “Trapper of the Year” (2023, via Signal Records/Columbia) and a long list of collaborations across the Detroit and greater Midwest indie trap circuit, he’s known for cartoonishly confident hooks, hard trap drums, and a chant-ready delivery. On “Carry and Conceal,” he slides into AyooLii’s Milwaukee pocket like he’s been there the whole time, trading bars that feel both menacing and weirdly fun, which, honestly, is the Certified Trapper special.

The production leans into exactly what you’d hope for from a pairing like this: punchy drums, a low-end that rattles the trunk, and just enough space for both artists to flex distinct personalities without stepping on each other’s toes. AyooLii keeps things quick and reactive, while Certified Trapper anchors his verse with that trademark bravado. It’s a short, tight, replay-friendly cut, which is kind of the point.

The visual, put together by Run Along Forever, matches the track’s energy beat for beat. Expect tight edits, plenty of attitude, and the kind of street-level aesthetic that has defined the Milwaukee scene’s recent crossover moment.

Fresh off its arrival on DSPs in April 2026, “Carry and Conceal” feels like a checkpoint moment for both artists, proof that the Midwest underground pipeline is very much still cooking. If you’re plugged into where rap is actually moving in 2026, this collab is required listening.

Press play above, turn it up louder than your neighbors would like, and keep an eye on both AyooLii and Certified Trapper as they roll through the rest of the year.
