Gut-wrenching performance? (5,5)
I believe the answer is:
belly dance
'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" .)
