In the late 70s, a time of new departures, music has been redefined by countless "3-chord-dilettantes". Hippie-bourgeois, fossilized political debates and jazzrock-blabla have been torpedoed by the disregard of (musical) technical skills, by fun and political provocation.

At this time the teenagers Katrin Achinger and Matthias Arfmann formed their first punkbands. In joint sessions (when the others had already gone) the idea arose to continue working as a duo.
At Katrin Achinger´s request this "child" was named Kastrierte Philosophen. It was the year 1981. Tape releases, privately distributed, followed:
Kastrierte Philosophen/ Decadent Toys (C30) and Kastrierte Philosophen/Heroin live (C30).
Peter Bogner became inspired by these recordings and shot a movie about the band titled "Stählerne Träume in F-Moll".

In 1983 and 1984 they recorded at their own expenses the two EP´s "Kastrierte Philosophen" and "Kastrierte Philosophen/Lens reflects fear". For the release they borrowed the labelcode of the 39Clocks´s-label Psychotic Promotion, with whom they performed several shows in these years.
The BFBS radio-DJ John Peel played tracks from these records in his program and got his tongue twisted every time he tried to pronounce the bands´s name.

In 1984 a KP-demotape found its way to Alred Hilsberg. It made him visit the band personally straightaway to offer them a record-deal on his label What´s so funny about. During the following years various LPs emerged from this turbulent relationship; all of them were distributed by EFA.

In 1985 the KP recorded in the Studio Hardenberg/Georgsmarienhütte by Stefan Groß "Love Factory", their first album. On their tour, promoting this record, the band supported Velvet Chanteuse Nico.
Tim Renner produced a clip for the title song "Love Factory" for his video-magazine "Für eine handvoll D-Mark".

In 1986 "Insomnia", recorded in the Staccato Studio/Hannover by Michael Polten terrifies Label-owner Alfred Hilberg and he threatens to jump out of the window. Yet, for the first time, the band is internationally noticed (5/85 NME "Insomnia is the best LP 4AD never had, Birthday Party excepted"); the german press is enthusiatic as well ( Diedrich Diederichsen " This record is nerve-racking").
The LP´s first edition contains the 7" Single "Skin and Pain". This year the band plays two extensive tours through Germany, Austria and Switzerland. The first live-recording of the KP is produced by NDR in Hamburg´s Alabama Cinema in May 1986.

In 1987 "Between Shootings" is recorded in the Staccato Studio/Hannover by Michael Polten.
Radio broacasts in Sweden, a Scandinavia-tour and a tour in Germany with The Jesus & Mary Chain present the band the biggest popularity so far. At christmas 1987 Achinger/Arfmann play an unplugged concert in Hamburg´s Markthalle.

1988, the album "Tyrants & Poolsharks" contains live recordings from the first 7 years plus 6 unreleased, new tracks from the above mentioned solo show.
Achinger/Arfmann end their cooperation with Alfred Hilsberg. They split in mutual agreement.
WSFA releases the CompilationCD "Kastrierte Philosophen". The band changes to the label NORMAL/Bonn, distributed by Rough Trade.
The first release is the LP "Nerves", recorded in spring 1988 in Hamburg´s Ultraschall Studio by Folke Jensen. The first live-presentation of the new material takes place at Roskilde Festival in July 1988 on the New Stage (with the Young Gods and the Sugarcubes ).
The drummer Rüdiger Klose joins the band as a fix third member.
The official LP-presentation is in october in the Metropol/Berlin (with Blind Idiot God and Clock DVA) on the Berlin Independent Days. An extensive tour through various european countries follows. The first licence deals into foreign countries are made.

In 1989 Andrew Eldrith wants to do a remix of a KP song. The resulting 12" "Toilet Queen" gets very positive reactions, especially from France.
Klaus Maeck film director from Hamburg produces a clip for "Toilet Queen", in which Eldritch plays a minor role. In June 1989 the KP play the Bizarre Festival (with the Jesus & Mary Chain and Living Colour). First tours through east-european countries like Yugoslavia and Hungaria.

On 9/11/89 (the day the Berlin Wall came down) Achinger/Arfmann reject already existing material for new productions and decide to record an album dealing with the political changes of that time. They start the recordings at once.

1990 "Leipzig D.C." recorded in the KP-owned Knochenhausstudio/Hamburg and mixed in the Ultraschall Studio with Folke Jensen.
Cologne´s music-mag Spex excepted, there are hardly any reactions from the press on this controversal piece of music. The critic´s darlings do not receive any interview requests. Tensions with the label NORMAL arise. A tour through GDR and East-Europe in late summer 1990. The band decides to leave the stage for a longer period. The so-called farewell tour takes place in autumn 1990.
Achinger/Arfmann already work on the composition of a new Doublealbum 1991 "Eskimo Summer", recorded in Hamburg´s Knochenhausstudio as well as in various european cities. Out of 60 hours of recorded material they choose their favourite tracks for one half of the double-CD Box. The seconc CD contains 16 new, unreleased songs. The album is released as a limited edition Hardcover-Box. "Eskimo Summer" is the last KP release on NORMAL/Rough Trade.

In 1992 Matthias Arfmann releases his first soloalbum "Inner Ear" on Strange Ways Records/Hamburg; the distributor is Indigo. The material was recorded in the Knochenhausstudio. In December ´92 Arfmann and his band "The Naked Factory" present the new album live in different german and austrian cities (NDR live-recording)

In 1993 Katrin Achinger releases her first solo-album "Icaré", also on Strange Ways Records.
Along with her album her first book is published: ICARÈ.
In June this year the KP play live again for the first time on a Tour against Fascism (with Goldene Zitronen, Blumfeld, Absolute Beginner) through 3 east-german cities, organized by Hamburg´s Wohlfahrtsausschuß. In autumn Achinger/Arfmann start with the recording for a new LP.
