Gary Graff of Billboard.com reports that LINKIN PARK is hard at work on its fourth album, which will likely come out in 2010 according to co-frontman Mike Shinoda.

"It's moving," Shinoda tells Billboard.com. "I feel like we've been writing a lot. I'd say we've got about half the music done, though I shouldn't say halfway because who knows how long the next batch of songs will take. But all the material's just kind of coming together, and every week we meet up and assess the situation and for the rest of the week we just go and work on whatever we find exciting."

Shinoda says the group has decided on a producer but is not revealing that yet. He expects "an interesting transition" in the sound from 2007's "Minutes to Midnight", especially since singer Chester Bennington's upcoming solo project, DEAD BY SUNRISE — due out this fall — "is much more of a rock album," leaving the door open for LINKIN PARK to experiment with other approaches.
