Gut-wrenching performance? (5,5)

I believe the answer is:

belly dance

I'm a little stuck... Click here to teach me more about this clue!

'performance?' is the definition.
(I have seen 'Exciting performance' mean 'belly dance' so perhaps 'performance' could also mean 'belly dance')

'gut-wrenching' is the wordplay.
'gut' becomes 'belly' (I've seen this in another clue).
'wrenching' becomes 'dance' (I can't justify this - if you can you should believe this answer much more).
'belly'+'dance'='BELLY-DANCE'

Can you help me to learn more?

(Other definitions for belly dance that I've seen before include "Exciting performance" , "Entertaining manipulation of middle" , "Sensuous performance of Middle Eastern origin" , "Shaky performance" .)

I've seen this clue in The Times.
