Presentation by Tsvetan Dobrev and Simo Lazarov Bulgarian electroacoustic music The character of electroacoustic music from Bulgaria has many parallels with that of ex-Czechoslovakia. Simo Lazarov, the pioneer of this movement, studied extensively at the University of Prague. After creating his own personalised electroacoustic organ, he began to work for Radio Sofia on the analogue synthesizer "Synthy-100 ",EMS, London. Within the evolution of his work, the traditions of Bulgarian folk music remain evident. His composition "Slide-7s " became the first Bulgarian electroacoustic composition that received wide public acclaim. Thereafter he composed "The Games ", "Dialogue between Synthesizer and Computer " and "White Wind ", all of which received international recognition. In addition, he is widely known and respected in Bulgaria for his three albums, all of a more conventional nature, and also for his numerous live concerts. Simo Lazarov, has also written several film scores. The "first lady " at Bulgarian electroacoustic music is called Aphrodite Katmeridu. She was born in Sofia in 1956. She graduated from the Conservatory of Brno, where she studied composition with profesor Franz Emmert and electroacoustic music with profesor Rudolf Ruzicka. Apart from several pieces for Chamber Orchestra, she has also written many electroacoustic pieces; Vision 1-5, Bulgaria, Nirvana and Entering the Unknown. In her research, she seeks to unite the elements of electroacoustic and acoustic sounds. Another composer of the same generation, Tsvetan Dobrev, began his research at the studios of Radio Sofia with S. Lazarov. His first piece "Metamorphoses " was awarded first price at the international competition of Varese in Italy. After this he produced a composition that explored a new angle - dramaturgy of timbre - for a ballet entitled "Folks Sketches " and "Jazz Metastases ". His most recent composition "Sbogom diado ", an improvisation for computer sequencer and synthesizer, was produced in Radio Bratislava. Vladimir Djambazov was born in 1954 in Stara Zagora. After completing his post-graduate in Sofia, he studied electroacoustic music for a futher two years in Essen, Germany with profesor D. Rait. His first composition "Dialoque Between Horn and Tape Recorder " was awarded second place at Grenville, USA in 1981. He then produced "Rendez-Vous " for marimba and tape recorder, followen by "Slow Stagnation of Time ", "Hello and Adieu ", "Aleatromic " and "No Contact ", the latter being a trilogy dealing with problems of communication today, represented by transformations and mutations of the human voice. Today, a new generation of musicans continue to explore the possibilities of electroacoustic music with an additional format - that of digital technology. Presently, Adrian Pervazov is producing his first compositions at a private studio in Sofia. Yassen Vodemitcharov is pressently working at the CNSM in Paris. And finally, Yuliana Tochkova, who after completing her studies in composition and harp in Sofia, went on to study electroacoustic music at the Conservatory of Boulogne with professor Michel Zbar. At the moment she is studying in Bourges. She has composed a "cycle " entitled "Movement " and a piece entitled "Memories ", which was selected for last years competition at Varese. Valentin Lazarov, aged 17 is the youngest Bulgarian composer of computer music. His pieces however betray a serious and mature thinking in this field. Using brand new computers, he creates a peculiar sound enviroment, which prompt peculiar thoughts. His first composition "Slaves " treats the people who are constantly chained, but always long the coreted freedom of the spirit. After "Foution ",his third piece "The Observation of a Teenager " is an philosophical expression of the young composer.
