"His unrelenting explorations of non-idiomatic improvisation using trumpets, clarinet, vibrating speakers, egg cutters etc., made him one of the most active experimental musicians in Prague these days.

His most intensive collaboration arose from meeting with American musician/composer George Cremaschi (doublebass, electronics) with whom they established Prague Improvisation Orchestra, Los Amargados duo, an international dance-visual-music project Arthuur etc. In 2013 they released "Villa K" album and 2014 "Los Amargados with Susanna Gartmayer", limited MC with comics.

In 2011 he constituted Yanagi duo with Korean experimenter Ryu Hankil (alarm clock, typewriters). A year later they released their first album "clinamen" waiting for its second album to be released in Korea.

He is also member of psych-rock band Rouilleux.

During past years he started and still continues many projects: Poisonous Frequencies (with Federsel and DD Kern), NOIZ (with Thomas Lehn and Tiziana Bertoncini), Doppeltrio (with Maja Osojnik and Matija Schellander), Junk & the Beast (with Veronika Mayer) etc.

Since 1994 he plays as a DJ at Radio 1 in Prague (last years include the 13 raw programme), and was also a temporary student of gamelan music at Institute of Art of Indonesia in Yogyakarta (1997-1998)."

"Veronika Mayer *1977, Vienna, Austria Veronika Mayer is a freelance composer, musician and sound artist living in Vienna. Her works include instrumental and electroacoustic compositions, sound installations and performances with live electronics. She is active as electronic improviser, performing solo and in different collaborations, as well with visual ar tists . Pure sounds, natural given phenomena and material are the basis for her work, always emphasizing hardly perceptible elements, giving it a reduced but essential form and very clear structures, following the characteristics and inner behaviour of the sound itself. In her electronic performances and instrumental works she explores the continuous evolvement and expansion of single grains of sound. Focusing on the striking results of very smooth and minimal changes in sound modulation, she is observing the slightest differences and variations during these processes of manipulation. Her works have been presented at various festivals for contemporary and experimental music and soundart in Austria, Argentina, Czech Republic, Denmark, Ge rmany, Great Britain, Indonesia, Italy, Mexico, Slovakia, Switzerland, USA . She received commissions by Wien Moder n, Jeunesse Wien, ÖGZM, Ensemble Reconsil, Ensemble Platypus, Hörstadt, e_may/association LAUT, The International Rosario Marciano Piano Competition, amongst others. 2011 she received the S cholarshi p for Young A rtists by the Austrian Federal Ministry for Education, Arts and Culture, 2007 the Theodor - Körner Award for Sciences and Art. Veronika Mayer studied electroacoustic music with Germán Toro - Pérez and Karlheinz Essl, composition with Detlev Müller - Siemens and classical piano with Jochen Köhler at the University of Music and Performing Arts Vienna. She is a member of the Austrian network snim - spontaneous network for improvised music."
