Lambada is performed in capital (9)
I believe the answer is:
islamabad
'capital' is the definition.
(capital of Pakistan)
'lambada is performed' is the wordplay.
'performed' indicates anagramming the letters.
'lambada'+'is'='lambadais'
'lambadais' anagrammed gives 'ISLAMABAD'.
'in' acts as a link.
(Other definitions for islamabad that I've seen before include "Pakistan's capital" , "Asian city" , "Capital of Pakistan" , "city of Pakistan?" , "capital city" .)
