Onesidezero (also depicted as OneSideZero) is a five-piece music group from Los Angeles, California. Their style is often described as heavy melodic rock. Their songs are often very dark, with deep lyrics and slow bass lines.
Formed in 1997, the band recorded several demos before being signed by Maverick Records. Their first full length, Is This Room Getting Smaller, was released on November 20, 2001. The band toured for three years, alongside bands like Incubus, 311, Sevendust, Static-X, Soulfly, Soil, also appearing on HBO's Reverb with Linkin Park. The singles "Instead Laugh" and "New World Order" failed to push the album, and the band asked to be released from their contract. In 2003, Onesidezero disbanded and retreated to various side projects.
