Julia Wolf Put Kellin Quinn On “Lamb”

9 September 2026. Portland rain. Sleeping With Sirens voice on an alt-rock single. A lamb is a lamb.

Julia Wolf rel “lamb” on 9 September 2026 with Kellin Quinn of Sleeping With Sirens. She cut her parts first. He flew into a Portland studio she described as covered in clouds and rain. She had been living in his catalog for a year and asked because she was already in Oregon. He said his daughter already knew her songs.

Wolf had just taken “In My Room” to No. 1 on Billboard Alternative Airplay, the twelfth woman to do that. “lamb” is the next single, not a victory lap ballad. Melodic alt-rock. Her verse is the slaughter image. His verse is the apology from the other side of the same room. Pixel video in a 2000s game look.

Signal. What happened: Julia Wolf rel “lamb” feature Kellin Quinn. Exact track: single, 9 Sept 2026. When and where: DSPs, artist channels. Source: artist statement and DSP list. Why it matters: a chart-week alt singer pulled a post-hardcore voice into a song named like an offering. Earlier DRIFT: none on this title.

The hook is not a flex line. “A lamb is a lamb.” Soft hold, then the slaughter joke. Wolf’s register stays close. Quinn arrives on verse two with the higher, worn Sirens grain. Two points of view, one title. It is not a duet that trades choruses for radio. It is a handoff.

Production sits in the rock lane she has been walking since Pressure (2025), darker than the early TikTok pop, still melodic enough for the same rooms that sang “In My Room.” Headphones get the weather. Clips get the title chant. The video’s pixel grain is a costume. The song does not need it.

Deep End World Tour is already dated: 17 September to 4 December 2026, North America then UK and Europe. New songs were promised for those rooms. “lamb” is one of them, arrive eight days before the first headline date. Quinn is not on the tour poster. The feature is a studio visit, not a package bill.

Sleeping With Sirens built a decade on unpredictable song shapes. Wolf said that structure is what she wanted in the room. The risk is that “lamb” reads as a scene handshake more than a song. The tape argues otherwise if the second verse actually changes the temp. It does. He apologizes. She stays the animal in the title.
