Dance club (5)
I believe the answer is:
disco
'dance club' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for disco that I've seen before include "Modern dance hall or event, in brief" , "Dancehall with recorded music, in short" , "Public dance hall with recorded music" , "Dance club with recorded music" , "Demonic spirit" .)
