The Blabbermouth story did not provide a source for this story, so this is unconfirmed at the moment. Below is the full Blabbermouth report:
LIMP BIZKIT have received help from former
HELMET singer/guitarist Page Hamilton and KORN's Brian "Head" Welch during
the writing/recording sessions for the group's brand new CD, Less Is More,
tentatively due in the spring through Flip/Interscope Records. However,
it is presently unclear if Hamilton and Welch's contributions will make
the final CD, which is currently being recorded at a Los Angeles studio
with producer Rick Rubin (SLAYER, SYSTEM OF A DOWN, RED HOT CHILI PEPPERS).
32 songs have reportedly been written for the new album, with the bass
and drum parts on some songs having already been recorded, leaving frontman
Fred Durst to lay down his vocals.
