Thanks for all of the input.

Actually, both questions had to do with the other. I've been able to obtain several sources of demos Linkin Park did in their early days... A friend of mine got another and sent me the 'copy' of the disc. I should have probably specified how he should have copied it. It just delays me offering the torrent a bit.

As for the official/unofficial question, this would be the lineup:

1 track from the Ozzfest 2000 sampler CD (have a feeling this is too official).
2 tracks from a CD pressed by the band while they were trying to get signed.
4 tracks from a tape done in the early days, shortly after they got together.
9 tracks from a WB acetate submitted as the official demos.
The last 6 would be from the band's early EP, a self-pressed CD that's become a rarity that I ended up paying big bucks to own a true copy of...
