Clash in nightclub hop involving rockers' leader (11)
I believe the answer is:
discordance
'clash' is the definition.
(thesaurus)
'nightclub hop involving rockers' leader' is the wordplay.
'nightclub' becomes 'disco' (I've seen this before).
'hop' becomes 'dance' (I've seen this before).
'involving' is an insertion indicator.
'rockers' leader' becomes 'r' (I can't explain this - if you can you should give a lot more credence to this answer).
'disco'+'dance'='discodance'
'discodance' placed around 'r' is 'DISCORDANCE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for discordance that I've seen before include "Argy-bargy" , "Harsh noise" , "Conflict; lack of harmony" .)
