Band that shows promise getting buzz after gig (10,4)
I believe the answer is:
engagement ring
'band that shows promise' is the definition.
'engagement ring' can be an answer for 'band' (engagement ring is a kind of band). I'm unsure of the remainder of the definition.
'buzz after gig' is the wordplay.
'buzz' becomes 'ring' (buzz can mean a ringing noise).
'after' is a charade indicator (letters next to each other).
'gig' becomes 'engagement' (I've seen this in another clue).
'ring' after 'engagement' is 'ENGAGEMENT-RING'.
'getting' acts as a link.
Can you help me to learn more?
(Other definitions for engagement ring that I've seen before include "Proof of commitment" , "A sign of commitment" , "Union pledge" , "Love band" , "Token of partnership" .)
