Hybrid Theory is the first
EP by Hybrid Theory, a previous name of the band
Linkin Park. The album was recorded and self-released in May 1, 1999 through Mix Media. Later that year, the band changed its name to Linkin Park and
Hybrid Theory was re-mixed and remastered for another limited release in 2001 (with minor changes) in the credits and artwork for members of Linkin Park's fan club. Only about 1,000 copies were pressed and released. Original versions of the EP are hard to find and because of this; many bootleg or fake pressings of it have been sold on websites such as
eBay, and
Amazon.
