'this erupts?' is the definition.
The definition suggests a singular noun which matches the answer.

'a quiet intermission around end of recital' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano', ie soft or quiet).
'intermission' becomes 'pause' (synonyms).
'around' is an insertion indicator.
'end of' indicates one should take the final letters.
The last letter of 'recital' is 'l'.
'pause' enclosing 'l' is 'plause'.
'a'+'p'+'plause'='APPLAUSE'

'then' is the link.
