Opening to see recording of Small Island (6)
I believe the answer is:
eyelet
'opening' is the definition.
(eyelet is a kind of opening)
'recording of small island' is the wordplay.
'recording of' shows a homophone (sound like).
'small island' becomes 'islet' (I've seen this before).
'islet' is a homophone of 'EYELET'.
'to see' acts as a link.
(Other definitions for eyelet that I've seen before include "Hole in shoe through which lace passes" , "Small opening in needle for thread" , "Hole for fastener" , "Small ring, for shoelace perhaps" , "Small hole through which lace passes" .)
