Only loosely related, but Robin Sloan also wrote a truly excellent article about using neural nets to produce music: https://www.mcdbooks.com/features/sourdough

In his book Sourdough, he spends quite a while describing the music of the Mazg - a fictional group of European migrants. For the audiobook version of Sourdough, he trains a SampleRNN model on a particular genre of Croatian music, then has the model produce Mazg music. The description of machine learning is vivid and approachable, and the audio clips are fantastic.
