Straylight Run (originally from long island NY ) is the project of ex-Taking Back Sunday members John Nolan and Shaun Cooper. They formed in May 2003 when John and Shaun left due to personal differences with lead singer Adam Lazzara. John and Shaun had been writing songs while still in the old band that they felt didn't fit in with Taking Back Sunday's style, and the freedom of starting a new band gave them a chance to experiment with this new sound. The band's title is taken from a chapter of William Gibson's novel "Neuromancer."

The band gained popularity early on through word of mouth after they released 6 demos available for download exclusively on their website. They then went on to release a self-titled full-length and more recently a 6 track EP Prepare to Be Wrong. The band currently consists of John Nolan (vocals, guitar, piano), his sister Michelle DaRosa (vocals, guitar, piano), Shaun Cooper (bass) and Will Noon (drums). The band recently added a new song titled "The Miracle That Never Came" on its myspace.

Straylight Run's latest album, The Needles The Space, was released on June 19, 2007.

On June 3, 2008, Michelle DaRosa announced on the band's myspace that she was officially leaving to pursue her own solo projects.
