Seemless was an American rock/metal group formed by ex-Shadows Fall/Unearth drummer Derek Kerswill, Killswitch Engage vocalist Jesse Leach, and ex-Overcast/Killswitch Engage guitarist Pete Cortese.
Formed in 2002 following Leach's departure from Killswitch Engage, Seemless was signed to Equal Vision Records, and released their first self-titled LP. They toured with Nonpoint, Trivium, In Flames, SOiL, Fu Manchu, Lacuna Coil, and several others.
In late 2012/early 2013 it was announced that Threshold of Pain Records, an imprint label of media company Nefarious Realm would be re-issuing their debut self-titled, Seemless on limited edition vinyl.
