'noisy bunch of trumpets and horns' is the definition.
I can't judge whether this defines the answer.

'generals vetoed a' is the wordplay.
I cannot really understand how this works, but
'a' could be 'an' and 'an' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for brass band that I've seen before include "Group of musicians, maybe military" , "Group of wind instruments" , "Musical group" , "on hand at cheap wedding?" , "cheap alternative to gold ring" .)

I've seen this clue in the Sydney Morning Herald.
