sword dance

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

'cutting-edge show' is the definition.
I can't judge whether this definition defines the answer.

'rioting crowd ends a' is the wordplay.
'rioting' is an anagram indicator (I've seen this in other clues).
'crowd'+'ends'+'a'='crowdendsa'
'crowdendsa' is an anagram of 'SWORD-DANCE'.

Can you help me to learn more?

(Other definitions for sword dance that I've seen before include "Performance involving sharp weapons" , "Potentially dangerous steps" , "Entertainment with blades" , "steps with much arm-waving" , "Pre-war ritual" .)

I've seen this clue in The Times.
