yes, she performed JUICY @ a-nation'06, there was even an audio recording from the concert somewhere
maybe in the future she'll release a DVD with inedit performances from a-nation, rhythm nation, and lots more of events she has attended. it would be so nice, she has had a lot of performances throughout her career that we haven't seen yet
for example this event at south korea
it's from 'feel my mind' era. she was talking in korean, so cute! and Rock Your Body performance looks so hot <3
