According to this story: Yahoo! News - 50 Cent, Foo Fighters & Corea Join Grammys Lineup, Chick Corea, the awesome jazz keyboardist, will be performing at the Grammys with Foo Fighters.
Being a fan of both Jazz and Rock, I'm intrigued by the potential of what could come out of this. I have several Chick Corea albums. He is quite an innovator. He's played everything from jazz-rock, what you'd call "traditional" acoustic jazz, wild and crazy jazz to jazz-classical with orchestras. I don't know Foo Fighters very well, but this should be interesting.
So tune in on Feb 8 to the live broadcast on CBS.
