8 Track Hybrid Theory Demo CD is a little known demo cd that was released in 1999 some time after the release of Hybrid Theory EP. This demo cd contains demos for In The End, By Myself, Points of Authority, Crawling, Carousel, Part of Me, and And One. With one original track called She Couldn't. The song is not released because some part is from a song called The High and Mighty - B-Boy Document 99. 'Untitled', 'Points and Authority', 'SuperXero' and 'And One' are all identical to their counterparts on the 9-track demo CD. "Part of Me" and "Carousel" musically similar to the demos on the 9-track CD , but feature different vocal parts, including some different lyrics from both the 9-track demo versions and the HTEP versions.
