Psyclon Nine's main music contributor is lead vocalist, lyricist, multi-instrumentalist, and producer Nero Bellum, who is the only remaining original member.

Psyclon Nine began in 1999 when roommates, Marshall Goppert and Josef Heresy created an industrial metal music project called "Defkon Sodomy", influenced[1][2][3] by bands like KMFDM and Ministry.

Bellum met with European NoiTekk record label executive Marco Gruhn at a San Francisco Grendel show, and persuaded him to sign Psyclon Nine.

The album also featured a cover of the Ministry song “You Know What You Are.” In 2005, Nero Bellum met Rotny Ford of the industrial metal band Nocturne on the social networking site LiveJournal.

In October, the band opened for Mushroomhead again on their second North American tour with Josef on guitar and keys, Abbey on bass, VII on synth, and Daniel on drums.

Nero Bellum appeared on the internet channel NoisescapeTV in 2008 and said that he was in the studio working on an album entitled We the Fallen, and has decided to stray away from the harsh EBM music style and incorporate a more black metal meets dark ambient sound.

In early 2009, a MySpace blog Q&A video announced that Rotny Ford had rejoined the band, after reconciling at the funeral for Bellum's mother.

It reached the top Billboard 500 sales and was sold in every Hot Topic store in the United States, which gave the band huge exposure across the nation.

In mid 2013, Bellum recorded guest vocals on extreme metal / aggrotech band Dawn of Ashes's new album, Anathema, and was featured in their music video for "Poisoning the Steps of Babel".

In late 2013, Bellum, Eric Gottesman, and Jon Heresy (the original members) played a one night show in San Francisco at the DNA Lounge, a venue that the band frequently performed at when first getting started.

It featured remixes of Order of the Shadow: Act I from Falling Skies, Die Sektor, Alien Vampires, Dismantled, MissFit Toys, Modern Weapons, and Life Cried.

After the Bandcamp controversy, Ford and Siren posted on the official Psyclon Nine Facebook page that both had quit the band due to Bellum disappearing again, stating they felt he was irresponsible.

Due to Ford and Siren quitting the band and other misunderstandings, Nero felt it was time to put an end to Psyclon Nine, canceling their European tour.

[5] Nero Bellum announced on his personal Facebook page that he wanted to perform one last series of concerts before putting an end to the band.

Live band members consisting of guitarist Dorian Starchild, bassist Brent Ashley and drummer Kriz DK joined Psyclon Nine for their final performances.

Psyclon Nine's Bandcamp page was also given a major graphical update in late 2015 and continues to carry older legacy merchandise along with signed albums and new apparel designs for fans to purchase.

On October 30, 2016, Psyclon Nine performed a special live set featuring songs exclusively from Divine Infekt, INRI and Crwn Thy Frnicatr.

Nero Bellum was also brought on stage during Dawn of Ashes' song "Poisoning The Steps of Babel" to provide vocals during his verse featured on the album.

Psyclon Nine kept this tour exclusively "electronic" based sets in that it was performing songs from the albums "Divine Infekt", "INRI" and "Crwn Thy Frnicatr".

The band debuted the first new single from the upcoming album called "Crown of the Worm" during a live performance in Downey, CA on February 24 as well as a teaser via Nero Bellum's official YouTube channel.

Described as, "the epitome of dark metal industrial," with violent, mechanical drums, scathing vocals, punishing guitars and evil electronics.
