Edgy reggae duo repeat performance (4)

I believe the answer is:

redo

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

'repeat performance' is the definition.
'redo' can be an answer for 'repeat' (I've seen this before). I'm not sure about the 'performance' bit.

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for redo that I've seen before include "Create again" , "Redecorate or repeat action" , "Make anew" , "Perform (action) again" , "Carry out again" .)

I've seen this clue in The Irish Times.
