I stumbled across this extract in a book featured on google.books. It's a bold claim I had not heard anything about before. Does anyone else know anything about it?
“The Turkish musician Kudsi Erguner relates, for example, that in 1989 he discovered with astonishment an exerpt of one of his improvisations (taksim) on ney flute in Revolutions by Jean-Michel Jarre (1988), a work commissioned and composed for festivities celebrating the French Revolutions’s bicentenary. Jarre had indeed acquired from the sound engineer, Xavier Bellenger, an unpublished recording of Erguner, produced at Senanque Abbey (the narrative does not say under exactly what conditions). An excerpt of this recording had then been ‘reworked’ and harnessed by Jarre, using current sampling techniques. The file for the prosecution instituted by Erguner on Jarre revealed that in 18 months Jarre had received 690,000 French francs as rights for the composition: none of this had been paid to Erguner, who was not even credited on the cover of the CD in question. The judicial confrontation turned to Erguner’s advantage but resulted in his receiving a modest indemnity, which did not even cover his lawyer’s expenses.â€
