Endless street party getting noisier (9)

Ross

I believe the answer is:

crescendo

I'm a little stuck... Click here to teach me more about this clue!

'getting noisier' is the definition.
I can't judge whether this defines the answer.

'endless street party' is the wordplay.
'endless' means to remove the last letter.
'street' becomes 'crescent' (No).
'party' becomes 'do' (do can informally mean a party).
'crescent' with its last letter taken off is 'crescen'.
'crescen'+'do'='CRESCENDO'

Can you help me to learn more?

(Other definitions for crescendo that I've seen before include "Rising noise" , "Building up of sound" , "In music, a gradual increase in loudness" , "Conceders (anag.)" , "Peak of intensity" .)

I've seen this clue in The Times.
