Linkin Park

Speaking to MTV News, Mike Shinoda of Linkin Park said, "The Transformers collaboration has been really fun for us. I mean, we grew up playing with the toys," Shinoda explained. "When we first got approached on the first one, we said yes based on the idea of taking that thing that we loved so much and bringing it to life in a modern way. As it's gone on, that's still a big part of it for us."

As opposed to the heftier sound of their first two Transformers songs, "Iridescent" is a more contemplative, hopeful ballad. "We put out the record in the late part of last year and even though it's never been a single up until this point, [when we played it live] you could really hear the singing pick up momentum during that song. It was just something that seemed a natural fit," says Shinoda.

He added, "We loved that part of it when we were in the studio, but Michael actually loved pairing it with the movie because there's something that he feels it speaks to about the story line."

Transformers: Dark Of The Moon will arrive in theaters on July 1. A release date for the soundtrack has yet to be announced.
