Kersey's formation in 2003 followed the death of vocalist Jody Taylor's earlier band. After having attended Strain's reunion and final show, guitarist Kris approached Jody, asking him to come out and front a new band he'd been working on for a while. Since the final nail had been driven deep into Strain's coffin, and having enjoyed being active in a band again, Jody agreed.
Things started off slowly, but over the following months the band's sound and lineup began to come together.
Kersey played its first show in the beginning of the summer of 2004. Shortly after the group's first show the band hit the studio with Vancouver producer Blair Calibaba (Gob, Sum 41, Propagandhi, By A Thread). Kersey entered Lemon Loaf Studios at the end of the summer, recording and mixing a three-song demo with Calibaba in three days. A copy of the demo was passed on to Let It Burn Records, the result of which is Kersey's Jesse Gander-recorded five-song CD EP, entitled Bloodshot, which was released in the spring of 2005. September 2005 saw the departure of founding member Scott Davis. Scotts decision was based on his desire to fulfill some personal goals he set out for himself. With Scotts departure, Kersey made some changes. Aaron has left his bass playing duties to switch over to second guitar. Kersey was happy to bring in good friend and ex Meanstoanend bass player Paul Dawson. After a month and half Kersey is ready to return to the stage and finish writing the material for a full length Lp.
