As well Ligeti was influenced by Conlon Nancarrow , writing the piano piece's "Vertige",
Conlon himself wrote a mechanical piano piece as a tribute to Ligeti for his 65th birthday.
"Dear Mr. Ligeti: About six months ago I was advised from Germany that they were sending me three records of your music. They just arrived. I am overwhelmed. Thanks for having them sent. For some time I have been very flattered by the things you have been saying about my music. Of course I knew that you were a famous composer, but I had not heard a note of your music. Well, now I have, and am very impressed. I haven't felt such excitement since Bartok and Stravinsky. By the way, are the String Quartets published? I would like to see the scores. I understand that you will be at the ISCM festival in Graz. I look forward to seeing you. Best regards, Conlon Nancarrow."
(a message from Nancarrows to Ligeti - 30 june 1982)
"Dear Mr. Nancarrow, thank you so much for your letter, it is the greatest pleasure for me. Since I know your music (i.e. since summer 1980 when I heard the first two records of your Studies) I love your music more than any other music of a now living composer. Since then I got also the third record and a number of scores published by Mr. Garland both in Soundings and separately. It's very hard to get your records in Europe, therefore -- I hope you don't object -- I made a great number of tape copies for friends, so your Studies reached even some East European countries.... I didn't know your address until your letter came...I'm very happy to meet you in Graz... I have the honour to introduce your music at the ISCM festival and I look very much foreward for this event and for your personal presence there... ' (a Ligeti's letter to Nancarrow - 20 august 1982)
