Milan Bachorek studied the piano with Milada Slachtova at the Pedagogic Faculty of the University of Ostrava (1954-1960), and from 1963 to 1966 composition with Miroslav Klega at the Ostrava Conservatory. Since 1960 he had worked as a music teacher at the People's School of Arts in Frenstat pod Radhostem, in 1965 he became a choirmaster of the amateur choir Radhost (until 1989). Since 1967 he was teaching at the Ostrava Conservatory, at first music theory, later on composition as well. In 1992 was appointed the director. He is also an active music critic and populariser. Since 1974 he had been holding the appointment as Secretary of the local branch of the then Czech Composers and Concert Artists Association in Ostrava, and after its transformation into the Association of Musical Artist and Musicologists in 1990 he became the chairman of the Ostrava Creative Centre (until 1992).
In his compositions, Milan Bachorek issued from a synthesis of 20th century classics heritage and ethnic melodics spread through the Beskydy Mountains foothills in Northern Moravia. In 1969 Ritornello per orchestra opened second period of his works, manifesting composer's joining new composition trends. Since then Milan Bachorek has followed these trends while on the other hand avoiding academic experiments and unemotional constructions. His compositions are remarkable for their colourfull sound, striking melodiousness, tectonic balance and a typical lyric-epic tinge, which applies even to his chorus works. Little Evening Music, a cycle of children's choirs, has been awarded the Czech Composers and Concert Artists Association Prize in 1983.
Among Bachorek's most successful works counts a loose cycle of three vocal-symphonic compositions, created through the years 1973-86 and connected by the choice of a serious subject and by used sound material. The cycle includes Lidice, a melodramatic tableau for solos, reciter, male and female chorus, percussion istruments and orchestra, Stereophonietta for soprano, baritone, percussion instruments, organ and two orchestras, and a kind of homage to composer's homeland and its people, Hukvaldy Poem for soprano, tenor, baritone, children's and female choir and orchestra.
