2009 release. Poème-Partition X was created by Bernard Heidsieck in 1960 and recorded in October of the same year. A few excerpts of the 1st and 4th movements were performed on November 22nd, 1960 at the Quatre Saisons Gallery in Paris, during the Festival of Avant-Garde Art. Poème-Partition X might be considered Heidsieck's first major work, whose duration (more than 40 minutes long) never allowed the author to give a public reading of it. Its destination was a record (released by Alga Marghen in 1996, starting the VocSon LP series, 36 years after its creation). Alga Marghen is proud to present this edition of Poème-Partition X, extended to the CD format and included in a luxury 96-page hardbound book. The book reproduces the complete score, a visual wonder and a major experimental printed work. Bernard Heidsieck's memories of a historic lecture at the Jean Tinguely atelier is included as an introduction, as well as his testimony on Ian Sommerville and Brion Gysin's "Dream Machine." Also on the CD is a lecture of extracts of Poème-Partition X accompanied by saxophone from the American painter Larry Rivers. This recording from 1962 was not included in the LP edition and is here presented for the first time. In August 1962, Bernard Heidsieck went with John Ashbery, the American poet, to dinner at the studio of Jean Tinguely and Niki de Saint Phalle. Larry Rivers had a studio in the same place and was also there. Tinguely prepared grilled meat, skewered on one of his rotating sculptures. After dinner Rivers returned to his studio and began to play, alone and for himself. He earned his living, at the time, by playing sax at an after-hours jazz club. So, while he was playing, Bernard Heidsieck joined him in his studio and suggested that they do an improvisation together -- domething that Heidsieck had never done before, and has never done since. Larry Rivers immediately accepted, and an appointment was set up at Heidsieck's home a few days later. August 6th, 1962. A dinner party was organized for the same guests who had been at Tinguely's place and this unique 17-minute improvisation was recorded, but until now never released. It was, however, presented at the first Fylkingen Text-Sound Composition Festival in Stockholm in 1968. Luxury hardbound edition.
