Steve Strange: Steven John Harrington (28 May 1959 – 12 February 2015), better known by his stage name Steve Strange, was a Welsh pop singer.  From the late 1970s he was a nightclub host and promoter.  He became famous as the leader of the new wave synthpop group Visage, best known for their single "Fade to Grey", and was one of the most influential figures behind the New Romantic movement of the early 1980s.

Jesse Leach: Jesse David Leach (born July 3, 1978) is an American musician from Providence, Rhode Island, and is the lead vocalist of the metalcore band Killswitch Engage.  He also fronts the stoner rock/heavy metal band Seemless, as well as handling vocal duties for the hardcore metal bands The Empire Shall Fall and Times of Grace.  In February 2012 he rejoined Killswitch Engage following the departure of vocalist Howard Jones in January 2012.  He currently resides in Brooklyn, NY with his wife, Melissa.

Seemless: Seemless was an American rock group formed by ex-Shadows Fall/Unearth drummer Derek Kerswill, Killswitch Engage vocalist Jesse Leach, and ex-Overcast/Killswitch Engage guitarist Pete Cortese.

The Empire Shall Fall: The Empire Shall Fall is a band formed by Jesse Leach with friends in 2008.  The band released their first independent album "Awaken" which was released on November 17, 2009.  Including Leach, The Empire Shall Fall consists of guitarists Jake Davenport and Marcus de Lisle, bassist Nick Sollecito, and drummer Jeff Pitts.

Blitz Kids: The Blitz Kids were a group of young people who frequented the weekly Blitz club-night in Covent Garden, London in 1979-80, and are credited with launching the New Romantic subcultural movement.  It was Andrew Czezowski (Ex manager of The Damned) and Susan Carrington who went on to start The Roxy club with Barry Jones that introduced Steve Strange and Rusty Egan to the Blitz in Covent Garden, which started the New Romantic Movement.  Among the many attendees were Rusty Egan, Steve Strange, Boy George, Marilyn, Alice Temple, Perri Lister, Princess Julia, Philip Sallon, Carl Teper and Martin Degville (later to be the frontman of Tony James' Sigue Sigue Sputnik).  Crucially, the club lay between two art colleges (St Martin's School and Central School) and became a testbed for student fashion designers who set London ablaze during the 1980s.  These included Stephen Jones, Fiona Dealey, Kim Bowen, Melissa Caplan, Stephen Linard, Chris Sullivan, Judith Frankland, David Holah, Stevie Stewart, John Galliano, Darla Jane Gilroy, Dinny Hall, Iain Webb, Simon Withers, Willy Brown, Richard Ostell, Rachel Auburn and more.  The Blitz began making headlines thanks to its outrageous styles of clothes and make-up for both sexes, subsequently documented by Gary Kemp in his 2009 first-person book, "I Know This Much".

Awaken (The Empire Shall Fall album): Awaken is the debut album by The Empire Shall Fall, released on November 17, 2009 through Angle Side Side Records, owned by The Empire Shall Fall's bassist, Nick Sollecito.  "Awaken" features the vocal talents of Killswitch Engage vocalist Jesse Leach.  The band cites its influences as At the Gates, Meshuggah, and Edge of Sanity.  "Awaken" draws heavily upon the band members' interests in jazz, punk, and experimental music.  The album reflects heavily on the themes of politics and transcendentalism.  Lyrically the album advocates positivity, unity, and empowerment.  Historical inspirations for the album have been cited as Jello Biafra, Benjamin Franklin, Cynthia McKinney, and Ron Paul.

Disarm the Descent: Disarm the Descent is the sixth studio album by American metalcore band Killswitch Engage.  The album was released on April 2, 2013, under Roadrunner Records.

Killswitch Engage announced the return of Leach in January 2012, after vocalist Howard Jones parted ways with the group.  The album received generally positive reception from professional critics.

In Due Time (song): "In Due Time" is the lead single from Killswitch Engage's sixth studio album, "Disarm the Descent".  The song is the band's first single to feature vocalist Jesse Leach since 2003's "The Element of One".  The song charted at no. 23 on the Active rock chart and no. 26 on the Mainstream Rock chart.

Visage discography: The discography of the British new wave band Visage consists of five studio albums, six compilation albums (including an E.P.) and numerous singles.  Formed in 1978, the band released their first single "Tar" on the short-lived Radar Records label in 1979, before signing to Polydor Records in 1980.  Their second single, "Fade To Grey", was released soon afterwards and became an international hit.  After several personnel changes, the group disbanded in 1985, but a new line-up emerged in the 2000s, again led by vocalist Steve Strange.  In 2013, the band released a new album, "Hearts and Knives", their first for 29 years.  The following year, the band released "Orchestral", a live album featuring various classic Visage songs remade with a symphony orchestra.  The band's final studio album, "Demons to Diamonds", was released in November 2015 (released posthumously following Strange's death in February that year).
