Hybrid Theory EP

Hybrid Theory is the first EP by Linkin Park, then known as Hybrid Theory. Recorded and self-released in May 1999, 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 made and released. Original versions of the EP are hard to find and because of this; many bootleg or fake versions of it have been made.
