Croc nest is destroyed for musical performances (8)
I believe the answer is:
concerts
'musical performances' is the definition.
(I've seen this before)
'croc nest is destroyed' is the wordplay.
'is destroyed' is an anagram indicator.
'croc'+'nest'='crocnest'
'crocnest' anagrammed gives 'CONCERTS'.
'for' is the link.
(Other definitions for concerts that I've seen before include "shows" , "Performances of music" , "Public musical performances" .)
