Formed in 1995, their first "official" release (their actual first release was called Paper or Plastic [1996], released through a small Winston-Salem-based label called Huel Records), A Sense of Coalition (1998) gained popularity on college radio stations[1] for a cover of Don Henley's "The Boys of Summer" (not to be confused with The Ataris' cover of the same song that became a mainstream radio hit years later).
With the milestone release, Division of Labor (1999), Codeseven found themselves at the forefront of the hardcore movement.
This album saw the band becoming less aggressive and more melodic, largely abandoning their hardcore roots in favor of progressive, experimental space rock as Cave In had done.
It was announced on July 1, 2010, that Codeseven would be playing a reunion show on August 20, 2010, at Greene Street Club in Greensboro, NC.
On August 2, 2010, it was announced the band would support Circa Survive alongside Dredg and Animals as Leaders on a tour starting October 15, 2010.
