Concerto for Improvised Alto Saxophone and Audiovisual Data is a digital art object by Massimo Magee, designed to be read by the computer as both a visual still image and as a piece of audio, these being two readings of the same file. The piece was shaped across both visual and audio domains functionally simultaneously, meaning that a change in the visual also affected the audio, and a change in the audio also affected the visual. When you look at the visual reading, you are also seeing all of the audio data; when you listen to the audio reading, you are also hearing all of the visual data. The piece was created with processed image data and live alto saxophone, with debts of inspiration owed to Eric Dolphy and Anthony Braxton, among others. Full piece 7777x5085px, 22min26sec. NFT includes full resolution image reading and lossless audio reading, plus a movie file with both image and audio readings.
