The Crüxshadows /ˈkruːʃædoʊz/ is an American dark wave and synthpop band currently based in Jacksonville, Florida, United States. They made their debut with the album ...Night Crawls In (1993), and have since released such albums as Telemetry of a Fallen Angel (1996), DreamCypher (2007), As the Dark Against My Halo (2012), and Astromythology (2017 & 2018). The band has an international fanbase and has toured North America, Europe, and Asia.

The band was originally formed in 1992 by Rogue, Sean Flanagan and Tim Curry, in Tallahassee, Florida. Rogue served as songwriter and lead vocalist, and also played drum machines and electric violins; Flanagan also played drum machines and provided sound synthesis and computer programming; and Curry also provided computer programming, as well as equipment and guitar work. They self-released their debut album, ...Night Crawls In, in 1993, initially only as a cassette.

In 1994, the Crüxshadows recorded and released a cover of T. Rex's "Ballrooms of Mars" on Old School Records, and re-recorded "Bloodline" from their debut release.

In 1996, the band released their second album, Telemetry of a Fallen Angel. Initially it was simply a self released CD, but it was acquired and released by Nesak International/Kato Records, and later released and distributed by Dancing Ferret Discs. Years later it would be acquired by Rogue's own label Wishfire Records.

In 1997, both Sean Flanagan and Tim Curry left the band shortly after signing a record deal with Nesak International/KATO Records. Rogue absorbed their interest in the band as well as their commitments under the new contract, and became the only member of Crüxshadows for a time. Determined not to be dragged down by the comings and goings of other members, Rogue learned to use synthesizers and computers himself to maintain Crüxshadows' musical direction.

Rogue started working on new material for the band's third album in 1998. He recruited several new players including Chris Brantley, Kevin Page, Rachel McDonnell, and Trevor Brown. The band resumed touring nationally and finished work on their third studio album. During this period the Crüxshadows signed an ill-fated deal with New England–based Mere Mortal Records to release The Mystery of the Whisper. A few months prior to putting out the disc, Mere Mortal was forced out of business due in part to its acquisition of a debt-heavy distributor. With a new album, but no label, the Crüxshadows eventually partnered with Patrick Rodgers' startup label Dancing Ferret Discs. The Crüxshadows would spend a little more than a decade signed to Dancing Ferret.

In 1999, with their new label and a new lineup, the band released The Mystery of the Whisper, Until the Voices Fade..., and Paradox Addendum. By this time "Marilyn My Bitterness" and "Monsters" had become staples on the dance floors of a re-invigorated American Gothic-Industrial club scene. Capitalizing on the success of these songs, the band toured the United States relentlessly over the years that followed. The band's song "Eurydice" occupied the top position in the category of New Wave for several months on the charts of digital music pioneer MP3.com.

In 2000, the band contributed a song titled "Deception" to Music from the Succubus Club, released by Dancing Ferret as an accompanying soundtrack album for the tabletop role-playing game Vampire: The Masquerade. This song was also released in a German language version titled "Täuschung". Although "Deception" never charted, it became one of the band's most popular and enduring tracks.^{[citation needed]}
