Or should I say, her official recordings are hard to find...
Someone on youtube has been posting audio of Ishida Ayumi TV shows. They've posted about 14 hours of stuff so far, they post 2 or 3 more files every weekend. What's interesting is with some of them someone was taking photos off the TV screen during the original broadcast, and the photos have been added to the video as a slideshow. (He/she also likes posting photos of their pet dog, called Ayu.)
I believe many of these performances don't exist in the TV archives so this is the only way you can see them.
This one is awesome...

Whoever encoded the audio has faulty equipment though, causing glitches.
Here's a glitch-free version of the audio:
