Stylish duet playing around recital's opening enter uninvited (7)
I believe the answer is:
intrude
'enter uninvited' is the definition.
(I've seen this before)
'stylish duet playing around recital's opening' is the wordplay.
'stylish' becomes 'in'.
'playing' indicates anagramming the letters.
'around' is an insertion indicator.
'opening' indicates taking the first letters.
The initial letter of 'recitals' is 'r'.
'duet' is an anagram of 'tude'.
'tude' going around 'r' is 'trude'.
'in'+'trude'='INTRUDE'
(Other definitions for intrude that I've seen before include "Trespass" , "Poke one's nose in" , "Push in unwantedly" , "Because of temperature, blue" , "Untried (anag)" .)
