The band was formed by harsh vocalist Brian Calzini and consisted of clean vocalist Jason Neil, drummer Bobby Scruggs, guitarists John Copeland and bassist Sanders Dukes.
After the band self-released their debut EP False Hope, Paddock Park were signed to Eulogy Recordings in Summer 2008.
The band parted ways with both of their vocalists, Calzini and Neil, during their first concert tour in the United States.
At the end of 2016, We Are Defiance would play a comeback show in February 2017 in Ocala with Paddock Park also performing.
Calzini stated he would like to work with Paddock Park again without their former members and re-group the band.
