The composer Lubos Sluka spent his childhood in the little town of Opocno. Following his studies at the grammar school in Rychnov nad Kneznou, and after graduating from secondary graphics school he was admitted to Prague Conservatoire where he completed his studies in three subjects - percussion with E. Špaček, conducting with A. Klima (1954) and composition with F. Pícha and M. Krejci (1955).
In 1951, Sluka was chosen as Arthur Honegger's student, as well as George Auric's assistant. However, his stay in Paris has been cancelled due to political reasons. The same reasons had considerably complicated his admission to the Academy of Performing Arts (AMU). However, he didn't give up his attempts to study there, and graduated at the Academy of Performing Arts in Prague (AMU) in composition with J. Ridky and P. Borkovec, film music with V. Trojan in 1959.
Sluka worked for most of his life as a freelance composer. From 1962 to 1963 he was employed as the program editor in Czech Television in Prague while simultanously arranging compositions and working as a singing coach and concert co-operator with Czech eminent singers. From 1963 till 1969 he'd worked in the music publishing company Panton as editor (since 1969 editor-in-chief). In 1976 Luboš Sluka had been suddenly suspended in a deliberate political process from his position, dismissed from his employment and persecuted. After the Velvet Revolution in November 1989 he had been active in establishing the new Society of Composers which became a part of the Association of Czech Composers, Concert Artists and Musicologists. He was elected the first chairman of its repertory committee. In February 1992 was voted the chairman of the Society of composers and in January 1995 the chairman of the whole Association of musical artists and scientists (AHUV).

Sluka\'s work is very complex and diverse (more than 350 compositions). It is dominated by chamber music compositions (more than 60 titles), which had been successfully started by Sonata for violoncello and piano from 1956. After an exceptional success at the composer's contest in Moscow (which had been presided by Dmitrij Shostakovic), this Sonata became a mandatory piece at several international interpretation contests, eg. in Rouen, Prague's Spring festival and elsewhere, and thanks to Pablo Casals - who included this work in his master courses - has spread all over the world.

Luboš Sluka had also paid a great heed to vocal and vocal-symphonic compositions (8 song cycles, 5 cantatas), film and television productions (70 full-length films, 30 television productions, 3 musicals and 5 TV serials), as well as to orchestral music (80 pieces) and to so called popular music (80 compositions). He also wrote a lot of music for children, youth and musical amateurs.

Luboš Sluka's music has never submitted itself to any of so called New Music techniques but - primed by their assistance- he consciously follows up with the best traditions of some 20th century classical composers, especially inspired by the aesthetics and compositional style of Leoš Janáček, and by the deep and true sensibility of J. Suk's and B. Martinů's music.
