Publicise place in band (6)
I believe the answer is:
splash
'publicise' is the definition.
(as in splashing on a newspaper)
'place in band' is the wordplay.
'place' becomes 'pl' (abbreviation used in postal addresses).
'in' means one lot of letters goes inside another.
'band' becomes 'sash' (a band of material).
'pl' inserted within 'sash' is 'SPLASH'.
(Other definitions for splash that I've seen before include "Effect of fall into water" , "Effect of hitting water (or headlines!)" , "Throw liquid about" , "sensation" , "coming down of an astronaut" .)
