Jesse David Leach (born July 3, 1978) is an American musician, best known as the lead vocalist of the metalcore band Killswitch Engage.

Leach co-founded Killswitch Engage in 1999, but left the band in 2002; in February 2012, he rejoined the group following the departure of vocalist Howard Jones.

Corrin recorded four songs in 1996 which were eventually released as a CD by Propaganda Machine in 1998 after the band's breakup.

When he was not contacting his wife, Leach would sit alone in the tour van for hours after shows and simply wait for the remaining band members to return.

Leach's passion for his music combined with his emotional struggles at the time made him unable to exercise control over his screaming.

According to Mike D'Antonio in an interview for Killswitch's "(Set This) World Ablaze" DVD, "It seemed like there was always this dark cloud over Jesse's head."

The entire band played on stage (minus Adam D who had been out with an injury and was replaced by Andreas Kisser of Sepultura) with both Jones and Leach singing "My Last Serenade".

[citation needed] Killswitch Engage's sixth studio album Disarm the Descent was released on April 2, 2013.

Atonement, their eighth album, was released in August 16, 2019, featuring a duet with former vocalist Howard Jones titled "The Signal Fire".

Seemless is known for having explosive, emotive live shows and showcases Leach's new-found soulful blues-y vocals.

The Empire Shall Fall consists of Leach, guitarists Jake Davenport and Marcus de Lisle, bassist Nick Sollecito, and drummer Jeff Pitts.

The album's first single, "Strength in Numbers", was released on October 15 via Roadrunner Records as a free digital download for 72 hours for those who signed up for the band's mailing list.
