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

'sounds of brass' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'rings men finally cut from dual tracks' is the wordplay.
I cannot quite see how this works, but
'rings' could be 'oo' (multiple circles) and 'oo' is found in the answer.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
