This ambitious and beautifully produced two-CD set includes nearly all of Iannis Xenakis' chamber music for strings, piano, and strings and piano combined. Chamber music constituted a small part of the composer's output, since large ensembles and large forms were vehicles more commensurate with the aesthetic of his monumental, granitic music. There are no small pieces here, though; in each of these works, ranging from solos to a quintet for piano and strings, Xenakis was able to express his uncompromising vision no less ferociously than in his orchestral works. While all of the pieces have an elemental character, many with a visceral punch, the actual sound of the music is surprisingly varied, and the individual works have distinctive and individual characters. In spite of the weightiness and rigor of the music, the tone is not necessarily heavy, and some pieces, like Evryali for piano and Dikhthas for violin and piano, have moments of what could almost be described as whimsicality.

Initially conceived as a moral and artistic response to human suffering, violinist Edna Michell's Compassion also became a touching tribute to her mentor and source of inspiration, Yehudi Menuhin, on his death in 1999. The 15 compositions commissioned by Michell for the project revolve around the themes of suffering and charity in fairly abstract or suggestive ways, with few programmatic, religious, or political points made beyond the allusive titles. As a practical matter for curious listeners, this CD is a comprehensive sampler of contemporary musical trends, and the leading lights of two generations of composers are generously represented in the CD's 80 minutes. Established figures such as Karel Husa, Lukas Foss, György Kurtág, Hans Werner Henze, Wolfgang Rihm, Philip Glass, John Tavener, Steve Reich, and Iannis Xenakis share the program with rising composers Shulamit Ran, Chen Yi, Yinam Leef, Betty Olivero, Poul Ruders, and Somei Satoh.

Collecting five CDs for about the price of three, this set of Boulez recordings is without parallel among the conductor's new-music releases. Imagine getting Boulez's celebrated single CD of Luciano Berio's Sinfonia and Eindrücke and his equally impressive single CD of Arnold Schoenberg's Pelleas und Melisande and Variations for Orchestra, bundled with four pivotal Elliott Carter works, Sir Harrison Birtwistle's electrifying …AGM…, Gérard Grisey's Modulations, Iannis Xenakis's Jalons, Hugues Dufourt's Antiphysis, and Brian Ferneyhough's Funerailles, and you have an idea how far this set stretches.

Exploring 20th-century repertoire – both acknowledged masterpieces and new discoveries – this 14-CD anthology reflects the diverse aesthetic strands of Pierre Boulez’s programming over the course of his ground-breaking and influential career. These Erato recordings, made between 1966 and 1992, feature composers otherwise absent from Boulez’s discography – Xenakis, Donatoni, Grisey, Dufourt, Ferneyhough, Harvey and Höller – and the first CD release of the interpretation of Stravinsky’s incantatory Les Soucoupes in the version for female voices and four horns.

Known for drawing unusual sonorities from conventional instruments, Xenakis strangely left the piano's potential for novel sounds unexplored. In these works, Xenakis stays on the keyboard without so much as a plucked string or any use of gadgetry to alter the instrument's sound. Although that might make these pieces appear less radical, even "safe," Xenakis exploits every other option available.

Violinist Irvine Arditti, pianist Claude Helffer, and the Spectrum ensemble conducted by Guy Protheroe produce consummate performances of the Greek avant-gardist's unwieldy chamber music. If you're familiar with Xenakis's career you'll know he was trained in mathematics and enjoyed a successful career as an architect. Such background might prepare you for the music's preoccupation with line, volume, and form in an unusually abstract way, but it won't prepare you for its visceral, almost primitive power. On Akanthos, the singer Penelope Walmsley-Clark must cope with what is surely one of the most ridiculous soprano parts ever written.

This album celebrates a musical rapport that has lasted for twenty years and, above all, a true friendship: ‘We’re like two sisters, on stage and in life’, as Patricia Kopatchinskaja and Sol Gabetta like to say. In parallel with their dazzling solo careers, they have frequently got together for concerts in trio or double concerto formation (like the one written for them by Francisco Coll, recently released on ALPHA580). But they have conceived their new recording for a rather rare combination, the violin cello duo – with the aim of choosing pieces they found interesting either stylistically or for the way they use the instruments.

„Electroacoustic Works“ celebrates the 100th anniversary of Iannis Xanakis (on May 29th, 2022), one of the most influential 20th century avantgarde composers. For the first time, the complete electroacoustic works of Xenakis are now available on record! All tracks have been newly mixed by longtime zeitkratzer sound engineer Martin Wurmnest and mastered by Rashad Becker and finally reveal their full sonic range and dynamics. Booklet with English / German liner notes by R. Friedl (zeitkratzer) and rare photos from the Xenakis archive.

After “La Légende d’Eer” in 2016, the PERIHEL series presents one of the milestones of electroacoustic music: IANNIS XENAKIS’ mindblowing 54-minutes oeuvre “Persepolis”, mixed from the original 8 track tapes by MARTIN WURMNEST and mastered / cut by RASHAD BECKER.
