Stick 'N' Move, Rhinestone, Fuse and Reading My Eyes are the only Xero songs anyone knows for sure even exist. I don't think you're gonna be able to find 'Pictureboard'.
Hmmm. I havn't heard it till now. Though didn't mike write breaking the habit around the Xero era? Could have been a demo, that was never released.
All we know about Pictureboard is that it was a Xero song that was performed live as Linkin Park with Chester on vocals one time, presumably at an early show in 2000. Mike mentioned this on the Fort Minor messageboard that it was (at the time) the only time a Xero song had been done with Chester singing. That of course has changed since then, when they played Reading My Eyes in Japan last year.
