Slamet A. Sjukur (30 June 1935-24 March 2015) was the founding father of contemporary Indonesian music. He studied and worked in Paris under Olivier Messiaen and Henri Dutilleux. He was a lecturer at IKJ (Institut Kesenian Jakarta) but because of his unconventional ideas, he finally had to leave. He has been living in Jakarta and Surabaya as a freelance composer, teacher and music critic. Developing the idea of minimax in music, his compositions are "notable for their minimal constellation of sounds and for their numerological basis which indicate the composer’s interest in a new ‘ecology of music’".This idea views limitation not as obstructions but as a challenge to work with a simple material, maximally.
