'chinese rock' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'percussion instruments welcome' is the wordplay.
I cannot quite see how this works, but
'instruments' could be 'gongs' (gong is a kind of instrument) and 'gongs' is located in the answer.
'welcome' could be 'hi' (I've seen this in other clues) and 'hi' is found within the answer.
No letters remain.
This may be the basis of clue (or it may be nonsense).

'in' acts as a link.
