The Hollywood Reporter has confirmation (and a quote) from Lionsgate:

Veteran producer and 12-time Grammy winner T Bone Burnett (Crazy Heart, Robert Plant and Allison Krauss’sRaising Sand) will team up with award-winning composer: Danny Elfman (Alice in Wonderland, Spider-Man) for an unprecedented collaboration. Burnett will also serve as the film’s Executive Music Producer, producing songs for the film and soundtrack. 

“The Hunger Games is such a special property,” said Lionsgate’s Head of Film Music Tracy McKnight in a statement. “It has worldwide mass appeal, but it’s also sophisticated, cerebral, soulful and rebellious. We needed a composer who can translate these qualities musically, and we have not one but two incredible artists in an absolutely thrilling first time ever collaboration.”
