One-21 was a punk-rock band from Philadelphia, Pennsylvania. They toured and recorded from 1995 to 2005, when the band broke up.

One-21 began as a garage band named "Uzziah".

The band produced an EP and 3 full length albums as One-21: "In the Year King Uzziah Died"(EP), "When the Dragon is Finally Laid to Rest", "One-21 (self-titled)", and "Grenade."

The band's lyrics have always reflected the Christian faith of the band members, and the musical style stayed solidly in the realm of hardcore punk of a style more associated with 80s punk bands such as the Clash. Their final two albums also featured songs with more overt political messages, generally of a more progressive nature. This is somewhat anomalous in the Christian music scene, which is generally either apolitical, or right-wing.

After the band called it quits in 2005, former members went on to form the bands Kill Hands and Fang Fang. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
