"And One" is the fourth song on the Hybrid Theory EP album. It is the band's first recorded song with Chester Bennington as lead vocalist. It changes tempos many times - starting out with distorted guitar riffs, elevating into a high-paced set of lyrics, and then slowing down into a rap solo. The beginning of the song before Mike begins rapping "Breaking a part..." sounds very much like Hybrid Theory and Meteora songs. Being on their unreleased EP it has not had much play. It is also on their EP titled Songs From the Underground.
