Later in 2002, Linkin Park released the remix album "Reanimation". It included the songs of "Hybrid Theory" remixed and reinterpreted by nu metal and underground hip hop artists. Contributors to the album included Black Thought, Pharoahe Monch, Jonathan Davis, Stephen Carpenter, and Aaron Lewis. The sound of later Linkin Park albums would involve experimentation with classical instruments such as strings and piano, both of which, along with the same elements of electronica from "Hybrid Theory", are prominently included in the band's second studio album "Meteora". As Shinoda explains the difference in the sound between "Hybrid Theory" and "Meteora": "That electronic element has always been there in the band – it's just that sometimes we bring it closer to the front."
