In Extremo (Latin for At the Edge; abbreviated InEx or IE) is a German Medieval metal band originating from Berlin.

Versions of well-known traditional/Medieval ballads make up the main part of their repertoire, but the band has written an increasing share of original material in recent years.

They became known at that time through frequent appearances at Medieval market meetings, at which they performed their acoustic pieces and sold CDs of their renditions of traditional songs.

On 11 April 1995, during the recording for that year's season, Michael Rhein (alias "Das letzte Einhorn", "The Last Unicorn") found the project name "In Extremo".

The increasing number of visitors, success of their CDs and the popular interest, as well as cross-pollination from groups such as Corvus Corax and Bathory, encouraged In Extremo in 1995 to attempt to start a band combining bagpipes and other traditional instruments with rock guitars.

The result was the current incarnation of In Extremo, a rock group that integrates modern instruments like the drum set, electric bass and guitar with the acoustic elements previously used for the Medieval songs, and which plays both types of music as well as a hybrid of the two.

The band is likewise noted for their conspicuous stage costumes and known for using pyrotechnics in their concerts, including Der Morgenstern playing cymbals which have been set on fire.

A group of travelling musicians called 'In-Extremo' plays their version of the song "Herr Mannelig", from the album Verehrt und angespien, by the gallows outside the Old Camp Castle in the second chapter of the game.

They rejected at that time an invitation to Top of the Pops to play "Küss mich" ("Kiss Me"), because it was, according to Das letzte Einhorn, not their environment.

In Extremo last participated on 9 February 2006, in the Bundesvision Song Contest of Stefan Raab for the Free State of Thuringia; Das letzte Einhorn was born in Dingelstädt and grew up in Leinefelde.

Besides the electric guitar, bass and drum set, In Extremo defines itself by unconventional (for a rock band) instruments mainly of Medieval origin.

They include hurdy-gurdy, bagpipes, Uilleann Pipes, shawm, nyckelharpa, harp, cittern, tromba marina, hammered dulcimer, Klangbaum and various types of drums and percussion.
