RE: Moyamoya disease- A Real life story

Do you happen to know, if she was able to deal with the more monotonous types of 'music', like African drums, or dance styles like minimal techno?

If you check on Youtube, you'll see that she is currently fully back into music.

I also wonder if other types of sounds, like a single tone, birds signing, or even human voices, were something difficult for her to grasp.

According to her article on Pitch Fork, she said that she could not understand basic language.

Wondering as well how she was able to retrain herself again and if the quality of her music is at least the same, better, or worse compared to before the illness and surgery?

Well, one can only assume that she got worse...but from what I've listened to, she's has only gotten better.
