Performed musical works without opening drinks (8)

I believe the answer is:

sangrias

'drinks' is the definition.
(sangria is a kind of drink)

'performed musical works without opening' is the wordplay.
'performed' becomes 'sang'.
'musical works' becomes 'arias'.
'without opening' means to remove the first letter.
'arias' with its first letter taken away is 'rias'.
'sang'+'rias'='SANGRIAS'

(Another definition for sangrias that I've seen is " Spanish wines with fruit etc".)

I've seen this clue in The Guardian.
