Band search round (5)
I believe the answer is:
combo
'band' is the definition.
(combo can mean a musical group)
'search round' is the wordplay.
'search' becomes 'comb' (combing is a kind of searching).
'round' becomes 'o' (round can mean a round object).
'comb'+'o'='COMBO'
(Other definitions for combo that I've seen before include "Music group" , "Small jazz group" , "Small (jazz or rock) band" , "group of players" , "Small jazz or dance band" .)
