Iannis Xenakis, born in 1922 in Greece, pursued varied interests in mathematics, physics, law, archaeology, and music without initially planning a career in music. Following his active involvement in the Greek Resistance, which led to severe injury and exile, Xenakis relocated to Paris in 1947. His passion for music deepened, leading him to seek guidance from Nadia Boulanger and others, although he ultimately found his path independently. Xenakis's compositions are known for their mathematical and architectural influence, evident in works like "Pleiades" (1979) and "Psappha" (1975), which showcase his fascination with percussion and complex rhythmic structures. "Pleiades" features six percussionists and is divided into movements that explore metallic sounds, precise tonal instruments, and a mix of both. The work reflects Xenakis's interest in spatial dimensions and mathematical laws to structure music. "Psappha" offers a solo percussion exploration, emphasizing rhythm over melody or harmony. The Kroumata Percussion Ensemble, known for their extensive tours and collaborations, have played together since 1978 and are full-time members of Stockholmsmusiken, part of the Swedish Rikskonserter. Their repertoire includes a wide range of percussion music, often collaborating with other musicians and artists. The ensemble's dedication to percussion music has earned them international acclaim.
