Soisong, the experimental electronic project founded by the late Peter “Sleazy” Christopherson and Ivan Pavlov (CoH), have announced “Soisong Book,” a hardcover publication documenting the project’s history. The book is released on May 22, 2026 through the official store and is listed as available from 22:05 CET.

The release is not exactly a standard music album. “Soisong Book” is a 160-page full-colour, faux-leather hardback edition, limited to 222 numbered copies. It documents the project from its first planning stages through later “after-effects” and draws largely on email exchanges between Christopherson and Pavlov. The book also includes private travel and concert photos, official announcements, manifestos, fake documents and audience photographic contributions.

Ivan Pavlov gives us some more info: “It took me quite some time to find and put together all these late-2000s cellphone photos and low-res images made for Myspace, to upscale many of them with the use of today’s technology, to select from a thousand of emails as few as possible… but the work didn’t feel hard at all.” And he adds: “The book is a proper Soisong release in the sense that the process of its creation has been fueled by the same joyful enthusiasm and sense of fun as every other publication, or action documented within”.

The book contains two compact discs affixed inside the cover. The first disc presents a pre-Soisong recording of a 2007 concert in Tokyo, where CoH and The Threshold House Boys Choir performed as separate acts. The second disc contains a new post-Soisong studio album by Julio Ecclesiast, the trumpet player who also appeared on the final album “xAj3z”.

About Soisong

Soisong was an experimental electronic music project formed in 2007 by Peter “Sleazy” Christopherson and Ivan Pavlov, also known as CoH. Christopherson was known for his work with Throbbing Gristle, Psychic TV, Coil and The Threshold HouseBoys Choir, while Pavlov worked under the CoH name. The project was located in Bangkok, Thailand.

The duo’s work was a combination of Pavlov’s computer-based music and Christopherson’s approach to artificial vocals and “South Seas” instrumentation.

The first release was “Soisong EP,” an octagonal tour CDEP issued in 2008 in disposable-design packaging. The release also used the title as a password for additional material on the project’s website.

The duo followed with “xAj3z,” the project’s first full-length album. The CD used octagonal packaging and carried a warning that it could only play in CD players with a flat horizontal tray.

The duo’s live activity included the 2008 Test Run Tour, with dates in Tokyo, Rovereto, Copenhagen, Bilbao, Amsterdam, Moscow and Athens. A 2009 reunion tour followed with shows in Linz, Moscow, St. Petersburg, Wroclaw and Cologne. The final Soisong show took place at Hau 2 in Berlin on June 5, 2010, without Christopherson.

After Christopherson’s death in Bangkok on November 25, 2010, later project-related releases continued to document the project’s archive. “Soisong Split” was published in 2012 and included Pavlov’s CoH “Soisong” EP together with unpublished Christopherson sketches made available through the project’s website. The official store lists the CoH “Soisong” EP as a two-disc octagonal release recorded in 2010 and 2012.

Dais Records announced the first wide vinyl reissue of “xAj3z” in 2025 as a remastered deluxe 2LP edition with one previously unreleased track. The Bandcamp edition was released on May 30, 2025 and added “Lom Tum Lai Kwee” to the tracklist.
