Petr Kofroň established an ensemble for contemporary music in 1983 known as the Agon ORCHESTRA, of which in the 90s he became the exclusive programme director and conductor. The orchestra is geared to Czech avant garde music of the eighties (J. Berg. Z. Vostřák, Jan Klusák, R. Komorous, M. Kopelent), contemporary alternative Czech music (J. Adamík, P. Graham, P. Kofroň, M. Smolka, M. Chadima. M. Grygar, M. Šimáček, V. Havel, F. Topol, M. Nejtek, M. Ivanovič, I. Acher) as well as world contemporary music (J. Cage, S. Reich, P. Glass, J. Adams, F. Zappa, E. Sharp, J. Zorn, A. Coleman, M. Gordon, D. Lang, H. Goebbels, B. Bargeld). Petr Kofroň has conducted the Agon ORCHESTRA both on prestigious stages in Europe -- Germany, Austria, Switzerland, France, Hungary, Poland, Latvia, Lithuania, Estonia, Holland, Denmark.

The critics of the journal Stereo & Video declared the CD Graphic Scores and Concepts as the best recording of serious music in 1996. The concert performance of the opera The Fall of the House of Usher by Glass was nominated in 1996 for the prize of Radio Classic as “the event of the year”, and the stage performance of the same opera in the State Opera Prague (directed by Petr Tyc) was declared the best opera staging in 1999 based on a questionnaire conducted by Divadelní noviny (Theatre newspaper).

Burian. J. Pokorný. K. Brožek. M. Dočekal, M. Čičvák, J. Heřman, D. Balatka, Z. Plachý).
