There are several videos of ayu performing live before her debut. She performed on TV from 1994 to 1995. Almost all these performances are from Idol On Stage (at least that's how the show is called in descriptions).
Personally, I think she sounded much better there than during her early avex days and I think ASFXX would be a lot more enjoyable (vocal wise), had she used her actual voice.
I've made a playlist with all her early performances & when they took place, if anyone would like to check them out:

One performance was part of "TK Music Clamp" and iirc, TK is the one playing bass and doing background vocals. At least that's what I read but don't quote me on that.
Also, here is a non-romanized list of all the songs and their original artists:
Correct me if there are any mistakes.
