Record revolutionary coming to a point (7)
I believe the answer is:
tapered
'coming to a point' is the definition.
(I've seen this before)
'record revolutionary' is the wordplay.
'record' becomes 'tape' (taping is a kind of recording).
'revolutionary' becomes 'red' ().
'tape'+'red'='TAPERED'
(Other definitions for tapered that I've seen before include "Narrow" , "Getting smaller towards the end" , "Reducing to a final point" , "got slimmer" , "Predate (anag)" .)
