I heard about an earlier release, and it has a theory that makes sense. here it is from the website 411.com(i think thats the name.)
According to various sources (some of which are close to the band), Linkin Park is secretly readying their next studio album.
The album doesn’t have a title yet, but it does have a tentative release date and tracklisting. The album will supposedly come out on September 24 of this year and will feature the following tracklisting:
1. Awaking
2. Losing Faith
3. Trapped Deep Inside
4. Thoughts Will Remain
5. Getting Through It
6. Silence
7. Silhouettes
8. Out Of Breath
9. Free Your Mind
10. Carrying The Weight
11. Behind Those Lines
12. Waste Of Emotions
13. Piece Of Mind
14. Reflections
Whether or not this is a simple rumor has yet to be determined, but there is something that can be shown as “proof” that they are keeping it a secret, in that vocalist Mike Shinoda has recently been quoted in saying that they band will wait a while before making their next album, yet they’ve been recording new material on a second tour bus that goes everywhere they do. While these recordings aren’t final copies, they get songs done and ready for when they are in the actual studio, which speeds up the process quite a bit.
For fans wondering why the band would keep recording a secret, consider this. Linkin Park are by far the biggest rock band out there right now, and not announcing it to the public will help keep some of the pressure of while in the studio, something that is a huge killer of bands.
