Codeseven

From Lastfm:

Codeseven was formed in 1995 as a melodic hardcore band in Winston-Salem, North Carolina. Their first release, A Sense of Coalition gained popularity on college radio stations for an intense 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 subsequent releases Division of Labor and The Rescue, the band continually became less aggressive and more melodic, eventually abandoning their hardcore roots in favor of progressive, experimental space rock, much as Cave In had done. Their final album, Dancing Echoes/Dead Sounds was released in 2004 on Equal Vision. In 2005, the band broke up in order to pursue different opportunities. 2010 sees their reformation and they are currently touring

From Wikipedia:

Codeseven was formed in 1995 as a melodic hardcore band in Winston-Salem, North Carolina. Their first "official" release (their actual first release was called Paper or Plastic , released through a small Winston-Salem-based label called Huel Records), A Sense of Coalition (1998) gained popularity on college radio stations 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 their milestone release, Division of Labor (1999), Codeseven found themselves at the forefront of the hardcore movement. With the departure of singer David Owen, they released The Rescue (2002). 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. Their final album, Dancing Echoes/Dead Sounds, was released in 2004 on Equal Vision Records. The following year the band broke up in order to pursue different opportunities.

It was announced on July 1st, 2010 that Codeseven would be playing a reunion show on August 20th, 2010 at Greene Street Club in Greensboro, NC. Following an overwhelmingly positive response, it was decided that they would continue to tour. On August 2nd, 2010, it was announced the band would support Circa Survive alongside Dredg and Animals as Leaders on a tour starting October 15th, 2010.
