Music research

[investigacionmusical]

Hello all!

My name is Alejandro, master student in music research at the International University of La Rioja (Spain)... I am currently conducting music analysis studies of recordings through Sonic Visualiser for my academic work. This requires quality recordings of the music I want to analyze: Philip Glass Etude for piano nº6 Book 1, performed by the composer.
I am contacting you to know if there is the possibility of downloading the audio files of these recordings to do my research work for the University since Spotify has the best audio quality that exists.

I would be very grateful if you could give me the information I need.
Sincerely yours,

Alejandro.
