We've seen snippets of the cinematic world of Panem — Jennifer Lawrence as blood-spattered, arrow-wielding Katniss crouching in the woods, Josh Hutcherson as her battle-worn fellow combatant Peeta lying in a clearing. What we haven't yet checked out from "Hunger Games" — and why would we, with no trailer yet released and the film not hitting theaters until March 2012? — is anything to do with the score, an all-star collaboration between T-Bone Burnett and Danny Elfman.

But that musical omission will be changing soon, as Burnett not only told MTV News that filmmakers will be releasing "Hunger Games" tuneage soon, but that one track will feature Lawrence herself.

"Yeah, we did," Burnett said when we asked if Lawrence had recorded anything in the studio. "And it was beautiful. She did great. She's singing great. Killer actor too."

Burnett's confirmation follows a blog post in June from the website of Echo Mountain Recording Studio in North Carolina, detailing Burnett's in-studio work with Lawrence. The post has since been deleted and Lawrence's musical contribution has not been confirmed. After our chat with Burnett on Tuesday at the "Big Lebowski" reunion in New York, though (spoiler alert), we know the 21-year-old actress in fact recorded "Rue's Lullaby," a song Katniss sings after Rue, a young tribute in the Games, is mortally wounded.

"Yeah, we did that. We recorded that," Burnett said about "Rue's Lullaby." "And it'll be coming out soon."

While Burnett and Elfman are ready to release Lawrence's recording, the two Grammy winners are only just getting started on their "Hunger Games" work. What they have planned has blown Burnett away. "It's 300 years in the future, so we can take all sorts of liberties," Burnett said of the story. "[Elfman's] got an incredible space he's put together. It's the most incredible studio I've ever seen and he's got drums and marimbas and a cimbalom — just crazy instruments everywhere. We're just going to go over there and rock out. I think we're just going to play together. We're going to do it together."

Check out everything we've got on "The Hunger Games."
