"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."

"Jon Rose started playing the violin at 7 years old, after winning a music scholarship to King's School Rochester. He gave up formal music education at the age of 15 and from then on, was mostly self-taught.

Throughout the 1970's, first in England then in Australia, he played, composed and studied in a large variety of music genres - from sitar playing to country & western; from 'new music' composition to commercial studio session work; from Bebop to Italian club bands; from Big Band serial composition to Sound Installations. He became the central figure in the development of Free Improvisation in Australia, performing in almost every Art Gallery, Jazz and Rock club in the country - either solo or with an international pool of improvising musicians called The Relative Band.

In 1986, he moved to Berlin in order to more fully realise his on-going project (of some 25 years): The Relative Violin). This is the development of a Total Artform based around the one instrument. Necessary to this concept has been innovation in the fields of new instrument design (over 20 deconstructed violin instruments including the legendary double piston triple neck wheeling violin, environmental performance (eg. playing fences in the Australian outback using the violin as a bow), new instrumental techniques (tested sometimes in uninterrupted marathon concerts of up to 12 hours long), both analogue (built into the violins themselves) and the more recently inter-active electronics (3 bowing to Midi systems)... plus using the mediums of radio (over 20 major International productions for radio stations like ABC, BBC, WDR, SR, BR, Radio France, RAI, ORF, SFB, etc including 'Eine Violine für Valentin', 'The Long Sufferings of Anna Magdalena Bach' and 'Breadfruit'), live-performance-film, video and television to create a new, alternative, personal and revised history for THE VIOLIN.

Jon Rose performs his group projects and solo music in upwards of 50 concerts every year - in North America, Japan, Australia, South America, China, Scandinavia and just about every country in West & East Europe. He is featured regularly in the main festivals of New Music, Jazz and Sound Art e.g. Strasbourg New Music Festival; New Music America; Moers New Jazz Festival; European Media Festival; The Vienna Festival; Ars Elektronica; The Northsea Jazz Festival; Dokumenta; Roma-Europa Festival; Festival D'Automne; Festival Musique Actuelle; The Berlin Jazz Festival, etc. Rose has also been invited to curate Contemporary Music Festivals in Germany (e.g. Berlin Urbane Aboriginale) and Austria (e.g. Wels 'Unlimited'). He has curated his own festival "String 'em up" of radical string players and their instruments, taking place in Podewil, Berlin in 1998 and Dodorama and V2, Rotterdam in 1999 , Tonic, New York in 2000, Mains D'Oeuvres, Paris in 2002, and IPR, New york in 2010.

Other films/videos include 'Café Central' and 'Shopping' (both made for ORF, Austria). The Rosenberg Museum does actually exist.

Jon Rose is also the originator of 4 books - The Pink Violin and Violin Music in the Age of Shopping (both published by NMA, Melbourne); "Music of Place: Reclaiming A Practice", and rosenberg 3.0 - not violin music. Jon Rose is currently performing Palimpolin - Hyperstring 4, one of a number of highly acclaimed works for violin and inter-active software. In addition there are performances of Violin Factory featuring large string orchestras and interactive video in Europe and Australia. His group projects include Strung, Violin Music in the Age of Shopping (with the likes of Chris Cutler, Lauren Newton, Otomo Yoshihide, etc); the infamous Berlin Noise-Impro-Rock Band Slawterhaus (with Johannes Bauer, Dietmar Diesner & Peter Hollinger); The interactive 'Badminton' game Perks, based on the musical innovations and perversions of Australian freak composer Percy Grainger; and there are five established improvising trios which are currently available... The Exiles (with Tony Buck & Joe Williamson), and The Kryonics (with Aleks Kolkowski & Matthias Bauer), Artery (with Chris Abrahams and Clayton Thomas), Futch (with Thomas Lehn and Johannes Bauer), Strike (with Clayton Thomas and Mike Majkowski) and the bicycle-powered chamber orchestra composition Pursuit.
