"Thomas Lehn was Born in Fröndenberg (Germany) in 1958. Since the early 1980s Thomas Lehn has been working as a author and performer of contemporary music. After studying recording engineering - piano with Prof. Wilfried Kassebaum - at the Music Academy of Detmold in Germany, studies at the Music Academy of Cologne with Peter Degenhardt and Prof. Klaus Oldemeyer (classical piano) and with Frank Wunsch and Francis Coppieters (jazz piano) completed his academical education. In the 80ies he took part on courses of Studio for pianistic interpretation held by Prof. Jürgen Uhde.

As an interpreting pianist he has been playing concerts since 1982 - performing both contemporary new music including numerous first performances and traditional composed music of the classical and romantical period. In 1989 he initiated the chamber ensemble Trio Dario and four years later the Mengano Quartett, performing compositions of the contemporary avant-garde, in particular numerous first performances of comissioned works. Developed parallel to his work as a pianist, since the early 1990s his major and widely reknown work has been performing and producing live-electronic music. Rooted in the experience of a wide spectrum of musical fields based on his background as an interpreting and improvising pianist in classical-, contemporary and jazz-music and having been involved in numerous other projects like music theatre, dance, multi-media, studio pre-/post-production etc., he has been developing an individual 'language' of electronic music.

The electronic equipment he uses consists of analogue synthesizers of the late 1960s, and since 1994 in particular the EMS Synthi A. Besides the substantial sound qualities of its analogue synthesis, the facilities of this modular instrument - for example to modify electronic sounds very directly as well as to combine and to control several parameters of the sound synthesis at the same time - allows him to spontaneously act in close contact with the various structural degrees of the musical process.

In 2000 his solo album Feldstärken had been released on German label Random Acoustics. Up today, his discography enclosures about 80 CD publications. Numerous appearances at major international festivals of contemporary musics and concerts tours in Australia, Austria, Belgium, Canada, Croatia, Czech Republic, Denmark, England, Finland, France, Germany, Hungaria, Ireland, Israel, Italy, Japan, Lebanon, The Netherlands, New Zealand, Norway, Poland, Portugal, Serbia, Scotland, Slovakia, Slovenia, Spain, Sweden, Switzerland and the USA give evidence of his international profile and recognition.

He has been involved in projects promoted and/or supported by the Goethe-Institutes in Belgrade, Boston, Bratislava, Budapest, Chicago, Copenhagen, Glasgow, Lille, Lissabon, London, Manchester, Marseille, Milano, Montreal, Palermo, Rome, San Francisco, Tel Aviv, Tokyo, Toronto, Warsaw, Wellington and York. His musical activities enclosure long term and newer ensemble collaborations as well as involvements in numerous specific single projects. Long term collaborations are ensembles like KONK PACK, TOOT, THERMAL, FUTCH, MIMEO, SPEAK EASY, 6IX, VARIO-34, as well as the duo works with Marcus Schmickler, Tiziana Bertoncini, Gerry Hemingway, Paul Lovens, Frédéric Blondy Urs Leimgruber and John Butcher. More recently formed ensembles are the duos with Benoît Moreau and with the video artist Kjell Bjørgeengen, trio formations with John Butcher involving pianists John Tilbury and Matthew Shipp.

Further he is pianist and founding member of the ensemble]h[iatus, an ensemble for interpretation and improvisation of contemporary music, whichs members are all experienced interpreters and improvisers. The ensemble compiles concert programs integrating/alternating notated and real-time-created contemporary music. It has been first-performing commissioned works by Vinko Globokar, Peter Jakober, Jennifer Walshe, Anthony Pateras besides performing compositions of the contemporary repertoire. Besides performing his own electronic music, in the recent years Thomas Lehn became more active as a synthesizer interpreter of electronic compositions. The realisation of Boguslav Schaeffer's Electronic Symphony - live performed in 2010 and 2011 - has been documented on the CD PRES Scores on polish label Bolt/Monotype. In 2012 he world premierred OCCAM VI for synthesizer solo by Éliane Radigue at Berghain Berlin during festival Faithful! and - together with KlangForum Wien - dort for synthesizer and 15 piece ensemble by Austrian composer Peter Jakober at musikprotokoll Graz and at Konzerthaus Vienna."
