Alga Marghen is proud to now present this new edition of "Poème-Partition X", extended to the CD format and included in a luxury 96 pages hardbound book, limited to 350 numbered copies. The book reproduces for the first time the complete score, a visual wonder and a major experimental printed work. Bernard Heidsieck memories of an 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 the saxophone of 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 Ashberry, the American poet, to dinner at the studio of Jean Tinguely and Niky de Saint Phalle. Larry Rivers had a studio in the same place and was also there. Tinguely prepared grilled meat, akewered 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. Something that Heidsieck had never done before, and have never done since! Larry Rivers immediately accepted, and an appointment was set up at Heidsieck home, for a few days later. August 6th, 1962.

A dinner party was organised for the same guests who had been at Tinguely's place and this unique 17 minutes improvisation was recorded, but untill now never released. It was, however, presented at the first Fylkingen Text-Sound Composition Festival in Stockholm in 1968.
