After the disbandment of Throbbing Gristle, he participated in the formation of Psychic TV along with Genesis P-Orridge and Geoff Rushton—Rushton later changed his name to John Balance.

[1] Christopherson participated in the reunification of Throbbing Gristle and, after his relocation to Thailand in 2005, composed an album for his solo endeavour The Threshold HouseBoys Choir.

[1] Christopherson worked on the first two Psychic TV albums, Force the Hand of Chance and Dreams Less Sweet, joined by Balance on the latter.

They recorded parts of the album The New Backwards at Nothing Studios in New Orleans, owned by musician Trent Reznor at the time.

[citation needed] In 2005, following the death of Balance, Christopherson relocated from England to Bangkok, Thailand and founded the solo project The Threshold HouseBoys Choir.

[1] He also released the final Coil CDs—The Remote Viewer,[5] Black Antlers,[6] ...And The Ambulance Died in His Arms[7] and The New Backwards[4]—on the band's own Threshold House label.

In addition to the CD releases, Christopherson also released a 16-DVD box set following his relocation, entitled Colour Sound Oblivion, that was produced in a wooden box, in which a fifteen-page booklet, the program for Balance's funeral ceremony and a large collection of 6-inch × 4-inch postcards (mainly tour photographs) were also included.

The band officially premiered in Tokyo on 9 March 2008 and later performed several shows in Europe, having self-released their debut EP.

As part of the tour, Soisong performed a live soundtrack to Derek Jarman's film Blue in Rovereto, Italy.

In April of the same year, Christopherson and Pavlov, alongside David Tibet, Othon Mataragas and Ernesto Tomasini, also performed a live soundtrack for The Angelic Conversation in Turin, Italy.

The release consists of a CoH Soisong EP by Pavlov, originally recorded in 2010, and a collection of four unpublished sketches by Christopherson that were made available on the band's website.

[citation needed] In 2010 Christopherson started collaborating with Hirsute Pursuit, featuring Harley Phoenix and Bryin Dall, via email.

[13] The final music that was ever recorded by Christopherson occurred in Bangkok, Thailand with a project named "Electric Sewer Age" that also involved musician Danny Hyde.

[14] Writing for The Guardian, Dave Simpson credited Christopherson with using digital samplers on-stage before the Fairlight CMI popularised sampling.

He later provided design work for SEX, the fashion boutique owned by Malcolm McLaren and Vivienne Westwood.

He directed over 40 music videos—for artists such as Rage Against the Machine, The The, Van Halen, Sepultura and Robert Plant—and was responsible for a high number of television commercials.

While we were spending time in 2009 with him we were pretty sick from the intense emotional stress of our ceremony in Nepal for the reliving and releasing of a beloved.

"I [Peter Christopherson] worked as a free-lance photographer and contributor, then promoted to an assistant to Hipgnosis before becoming a partner, and continued to act also after I officially left the organization.
