"GX Jupitter-Larsen (sometimes erroneously spelled Juppiter-Larsen) is an artist, based in Hollywood, California, who has been active in a number of underground art scenes since the late 1970s. Jupitter-Larsen has been involved in punk rock, mail art, cassette culture, the noise music scene, and zine culture. During the 1990s he was the sound designer for the performances of Mark Pauline's Survival Research Laboratories. His best known work is as the founder of the noise act The Haters, who have performed all over the world, and appear on over 300 CD and record releases

Underlying all of Jupitter-Larsen's work's a peculiar mix of aesthetic and conceptual obsessions, particularly entropy and decay, professional wrestling, and a self-created lexicon consisting mainly of personalized units of measurement such as polywave, the totimorphous, and the xylowave. In 1985, Jupitter-Larsen invented his own number system. Jupitter-Larsen says his transexpansion numeral unit (TNU) explore the distance & separateness in between linear counting locations that do not neighbor each other. When arranged in order, the TNUs form a spiral around the standard linear numbers. If one assumes that each individual linear number is a particular location along a counting order, then each individual TNU would be the distance between two selected linear number locations. Where the TNUs have been placed is unimportant. What is important is that anyone can make up their own personal numbers to symbolize any numeral interrelationship that Jupitter-Larsen's do not. Instead of a way of doing arithmetic, what you end up with here is an emotional & philosophical barometer. The base TNU is I (pronounced a) which is located in between 1&4 but not 2&3.

In an article entitled "30 Years of the Haters" which appears in the premiere issue of the magazine As Loud as Possible a number of early performances by Jupitter-Larsen are listed. In most of these performances, enacted during the 1980s and 90s, whole audiences were led by inside agitators to actually ruin or destroy the venues that the performances were taking place. However a number of Jupitter-Larsen performance art events that are mentioned in numerous issues of the 1980s mail art zine KS are often non-confrontational projects. Such as the artist counting garbage cans while walking down a street by himself. His latest performance piece entitled "Loud Luggage / Booming Baggage", first performed in 2010, has The Haters operating amplified suitcases, shaking and banging them about till the luggage eventually breaks.

From 1982 to 1986, he submitted a black video tape entitled Blank Banner to over forty video festivals. It was screened in nine. In 1994, using an all female cast, Jupitter-Larsen produced a short lesbian vampire film entitled "Holes On The Neck". The film's narrative is of a group of vampires who work and play on their garlic farm. Their human lovers desire to become vampires themselves, and so lure these garlic farmers into initiating them. In 2013, Jupitter-Larsen's first feature-length movie entitled "A Noisy Delivery" premiered in Leeds England and New York City. The movie is about people who go to the post office for philosophy instead of postage.

There are three published novels written by Jupitter-Larsen. Raw Zed and The Condor was published by Blood Print Press in 1992. Sometimes Never and Adventure on The High Seas were both published in 2009 by Crossing Chaos. These novels are without chapters. Instead, Jupitter-larsen uses passages of random letters to represent nothingness, sections of entirely self-invented words to represent the spiritual, and regular words to represent the physical. A book of French translations of his essays and short fiction, entitled Saccages has also been published by the Lausanne Underground Film & Music Festival and Rip on/off. Vincent Barras, who has translated John Cage's Silence into French, wrote one of the book's introductions.

According to Experimental Sound & Radio, MIT Press, 2001, since 1983, Jupitter-Larsen had performed over 3500 hours of live radio art on 31 different stations in 11 countries."

"Leif Elggren (born 1950, Linköping, Sweden), is a Swedish artist who lives and works in Stockholm.

Active since the late 1970s, Leif Elggren has become one of the most constantly surprising conceptual artists to work in the combined worlds of audio and visual. A writer, visual artist, stage performer and composer, he has many albums to his credits, solo and with the Sons of God, on labels such as Ash International, Touch, Radium and his own Firework Edition. His music, often conceived as the soundtrack to a visual installation or experimental stage performance, usually presents carefully selected sound sources over a long stretch of time and can range from mesmerizingly quiet electronics to harsh noise. His wide-ranging and prolific body of art often involves dreams and subtle absurdities, social hierarchies turned upside-down, hidden actions and events taking on the quality of icons.

Together with artist Carl Michael von Hausswolff, he is a founder of the Kingdoms of Elgaland-Vargaland (KREV) where he enjoys the title of King.

Elggren spent five years at the Academy of Fine Arts in Stockholm, specializing in drawing, design and bookprinting. In the late '70s he began to associate with performance groups, meeting people like Hausswolff and Thomas Liljenberg. With the latter he formed Firework in 1978, a duo that put up exhibitions and performances. Around the same time he purchased a press and started to publish art books.

In 1988 he formed the duo Guds Söner (The Sons of God) with Kent Tankred, whom he had met four years earlier. The duo excels in creating long, puzzling stage performances that give equal roles to physical action (or inaction) and soundtrack (live or taped) with themes such as violence, love, the quotidian, food and royalty.

Elggren released his first 7" records in 1982 and 1984 on Hausswolff's label Radium. A first solo LP, Flown Over by an Old King, came out in 1988. The inception of Firework Edition in 1996 allowed Elggren to release more of his music and the growing popularity of installation art in avant-garde music circles (thanks to its ties with experimental electronica) has given his work more international exposure since the late '90s. Other key solo works include Talking to a Dead Queen (1996) and Pluralis Majestatis (2000).

Together with Hausswolff, Elggren represented Sweden in the Nordic Pavilion at the Venice Biennale in 2001 (with Tommi Grönlund and Petteri Nisunen from Finland and Anders Tomren from Norway).

In 2007 he appeared (with John Duncan) at the Netmage festival in Bologna organized by xing and executed "Something Like Seeing in the Dark".

Leif Elggen is also a member of Guds Soner (or The Sons of God) with Kent Tankred."
