In 1961, soon after Toshi Ichiyanagi returned from the USA, two concerts were performed at the Soget su Art Center; "Toshi Ichiyanagi Concert" , at which some member of 'Group Ongaku' joined, a s well as "Toshi Ichiyanagi and Kenji Kobayashi Duo Recital", which recording is used for this album. It was a major opportunity for its audience to experience the works of Toshi Ichiyanagi and the avant-garde philosophy directly in front of their eyes. Six months later, John Cage made his first v isit to Japan for a concert tour. Of course, then the Japanese music scene would be struck by a huge "shock". So we can consider the recital by Ichiyanagi as a "quiet shock" before the "storm".
DISC 1: Sylvano Bussotti (1931-) : Music for violin Italy-born Bussotti is a composer, a director and a designer but also well known as a multitalented person. At an early age, he began work on a graphic score. The music he wrote had quality but it was also visually interesting. For this performance, Kobayashi took a unique style. They used overdubbe d violin sounds from a tape, which perhaps Kobayashi helped to record, and added a live performance of piano and percussion as well as some [sounds of] object.
Morton Feldman（1926-87）: Duet for violin and piano Along with John Cage, Feldman is one of the leading figures from the New York experimental music sce ne. He is also well known as a soft sound composer as well as for an interesting episode when he inv ented graphic notation. Feldman was a productive composer but he often gave less creative simple tit les to his music, for example, by referring a composition to the musical instruments.
Toshi Ichiyanagi（1933-）: The Pile / For String #2 (simultaneous performance) 'The Pile' is a piece composed for arbitrary musical instruments. At the concert, the composer him self performed with a method of playing the internal parts of a piano along with Yoko Ono's voice w hile Juunosuke Okuyama assisted him as an engineer, which made it the first and only real piece with live electronics . Like John Cage often taking this method for his work, they made a simultaneou s performance for this piece, 'For stringed instruments, the second movement' by Kenji Kobayashi. The only instruction in the score was; "Through the whole performance one should only play one note " . The piece was not only performed throughout the sixties but also is played today.
Anton Webern（1883-1945） : 4 Pieces for violin and piano, Op.7 Along with Schoenberg and Berg, Webern belonged to the New Wienna School of music. Preceding Feldman , he was a soft sound composer and had a particular taste about extremely conscious tones. Unlike ot her pieces on this album, this piece was composed in the very early period in 1910.
La Monte Young（1935-）: 561 to Henry Flynt  La Monte was one of the composers who created pieces that were later categorized as Minimal Music. B ut most notably, he was a member of Fluxus, which we shouldn't forget. This piece is very conceptua l. The same note should be played for arbitrary number of times that was pre-determined. It was perf ormed at this concert for the first time and Ichiyanagi played clusters with both arms. By the way, Henry Flynt (1940-) was a musician belonging to Fluxus.
DISC 2: John Cage（1912-92）: 34'46.776" A piece composed in 1954 and performed in the same year on October 17th for the first time at Donaue schinger Musiktage, a music festival, (simultaneous performance with '31'57.9864" for a pianist'). Later that year, a score was published under the title '31'57.9864" for one pianist'. In this re cording, apart from Toshi Ichiyanagi's piano and Kenji Kobayashi's violin, one can hear female nar ration in English and Japanese, about which there was no mention in any document at the time (assumi ng it as Yoko Ono's voice however it is not confirmed). Perhaps, Ichiyanagi reproduced it by referr ing to an early performance method of the piece  In a promotional document of the concert, Yuji T akahashi's name is written as another pianist. However, according to the musician, he canceled it a fter he got an offer of a simultaneous performance due to a technical reason.
