Band sacked woman missing vocal elements in hotspots (8,5)

'band sacked' is the definition.
I don't know anything about this answer so I cannot judge whether it can be defined by this definition.

'woman missing vocal elements in hotspots' is the wordplay.
I cannot really see how this works, but
'woman' could be 'w' (abbreviation eg in Woman Police Constable) and 'w' is present in the answer.
'elements' could be 'tins' (tin is a kind of element) and 'tins' is found within the remaining letters.
The remaining letters 'thompson' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
