Turn up records and incite ostentatious display (7)
I believe the answer is:
splurge
'ostentatious display' is the definition.
(I've seen this before)
'turn up records and incite' is the wordplay.
'turn up' says the letters should be written backwards.
'records' becomes 'lps' (LP is a type of record).
'and' is a charade indicator (letters next to each other).
'incite' becomes 'urge' (I've seen this before).
'lps' backwards is 'spl'.
'spl'+'urge'='SPLURGE'
(Other definitions for splurge that I've seen before include "Spend lavishly" , "Spend money freely, be extravagant" , "Spend a lot" , "Spend extravagantly" , "Bout of extravagant spending" .)
