When I bought "Hybrid Theory" I didnt quite know what to expect, but I know I didnt expect it to be so good. Chester Bennington's vocals are perfectly complemented by Mike Shinoda's rhymes. I thought it would be like Chino Moreno and Fred Durst joining together in the same band, and both canceling each other out, wanting to be top dog of the band. This could not be further from the truth. Neither vocalist wants to steal the show, and both get a fair amount of play during each track on the CD (except "Cure For The Itch"). Bennington's vocals are immaculate, with soaring screams to soothing lines. His voice is so dynamic and adds a extra dimention to what some other bands dont have. To mix it up furthermore Shinoda's rapping opens up a floodgate to what styles this band can take onboard. The music seems to be heavily influenced by hardcore and industrial rock, with a large slab of hip-hop added by DJ Joseph Hahn. His sampleing and timing is perfect overshadowing the likes of DJ Lethal. The riffs supplied by Brad Delson are heavy and are very catchy. The drumming supplied by Rob Bourdon is again heavy and sounds... well... great. This is a band which is going to go very, very far. I would reccomend this album to my pearents (well maybe not), or anyone who likes any form of rock music (except big indie fans). The next Nirvana have arrived.
