Agent 51 formed in 1995 and was originally called Area 51. They released three albums on various record labels before going on indefinite hiatus in 2005. Over the course of their career their music evolved from straightforward punk rock to incorporate aspects of classic rock and heavy metal.
Initially the band was part of a thriving local punk rock movement that included other groups such as blink-182 and Unwritten Law. Founding member Chris Armes had attended Poway High School with blink-182 member Tom DeLonge, and Armes' previous band Openfast had played as openers for blink-182 on several occasions. This experience contributed to the impetus for forming Area 51.
The band's original lineup consisted of Chris Armes on guitar and vocals, Jared Herndon on bass guitar, and Eric "Airwick" Davis on drums. Herndon soon left and was replaced by Greg Schneider, while Davis moved to second guitar and Rob Hunter joined as drummer. Shortly before releasing their first album the group changed their name to Agent 51 due to the fact that there were already several bands in existence using the name Area 51.
Their first album, Red Alert, was released in 1998 by local label Alphabet Records. The album gained them notoriety in the local punk rock scene, and an independent music video was filmed for the title track. Armes took the stage name "Broken Armes" at this time due to an injury he suffered in 1997 which left his arm in a cast. In order to record his guitar parts on Red Alert, he removed the cast himself and recorded while still injured.
Around this time the band began disseminating the mythos that they were rogue secret agents on the run from the government due to their knowledge of secrets related to extraterrestrial life. To match this theme the band wore matching black suits while performing. It also became common for the band to cover songs from classic rock and 1970s metal genres in concert, such as AC/DC's "You Shook Me All Night Long" and "Highway to Hell."
By the recording of their second album in 2000, Hunter had been replaced on drums by Mike "Mikey L" Levinson. The album, Just Keep Runnin', was released that year on the band's own label Suburban Hooligans Records. The music was faster and slightly less punk-based than Red Alert and included several songs that had become favorites in the band's live set over the last few years such as "Who's Gunna Riot?" and "The Last Pirate Standing." The album's artwork and liner notes greatly expanded on their secret agent mythos by describing each member as a rogue agent enhanced with super powers through extraterrestrial DNA and technology, as well as detailing their struggle against a secret government organization called "The Agency."
The band played on the Warped Tour that summer on the Ernie Ball side stage, winning Ernie Ball's Battle of the Bands competition. They also recorded the theme song for the short-lived San Diego public access TV show Radiation Nation. The song was later included on the 2001 Warped Tour compilation.
Just Keep Runnin' caught the attention of Billie Joe Armstrong of Green Day and his label Adeline Records, who rereleased it in 2001 with two bonus tracks recorded with new bassist Sean Scura, as Schneider had by then left the group. The band continued to tour, playing at San Diego's Street Scene and other festivals.
Agent 51's next album was 2003's Red and the Black, released on Southern California label Surfdog Records. With it, the band moved towards a sound more reminiscent of classic rock and heavy metal bands such as AC/DC, Motörhead, and Def Leppard. It also distanced them from their secret agent mythos by not mentioning extraterrestrials or conspiracies and by ceasing to wear their matching suits in concert. The song "She's My Heroine" received airplay on local rock radio station 91X, while "American Rock 'n' Roll" was used in the opening episode of MTV's Real World: San Diego and "Air Raid" was later used in the video game Big Mutha Truckers 2. The album was nominated in several categories at the 2003 San Diego Music Awards and won for "Best Punk Album."
Despite the band's growing popularity, however, Armes announced that he was leaving due to musical and financial pressures. Davis and Levinson formed 51 Guns in the summer of 2004, along with drummer Adam Rapps of Pivit. Agent 51 remained inactive until June of 2005.
