US prices on foreign drums (10)
I believe the answer is:
percussion
'drums' is the definition.
'us prices on foreign' is the wordplay.
'foreign' is an anagram indicator (foreign order of the letters).
'us'+'prices'+'on'='uspriceson'
'uspriceson' is an anagram of 'PERCUSSION'.
(Other definitions for percussion that I've seen before include "Drums etc." , "Impact" , "triangles etc" , "kitchen" , "Instruments played by striking" .)
