Endwell formed in Queens, New York in 2003 and started gaining popularity through local shows. After gaining enough experience through
various local shows, the band independently recorded and released their first EP titled The Missing Pieces in 2005. The band toured the
country for various hardcore bands in support of the new EP and began expanding their fan basis with their energetic live shows. They won a
Battle of the Bands, which earned them a spot on the Hellfest bill. Their minor success caught the eye of Bayside's front-man Anthony Raneri.
Bayside was signed to Victory Records and suggested to Endwell that they should attempt to get signed to the label. Members of Endwell grew
up listening to various Victory bands including Earth Crisis and Hatebreed.
