Dance most of jig in front of empty venue (4)
I believe the answer is:
jive
'dance' is the definition.
(I know that Jive is a dance)
'most of jig in front of empty venue' is the wordplay.
'most of' means to remove the last letter.
'in front of' is a charade indicator (letters next to each other).
'empty' says to hollow out the word (remove centre letters).
'venue' with its centre removed is 've'.
'jig' with its last letter removed is 'ji'.
'ji'+'ve'='JIVE'
(Other definitions for jive that I've seen before include "Swing music; dance" , "Nineteen fifties dance style" , "Fast dancing style" , "Jerky, jazz dance of the 1950s" , "Style of fast dance music" .)
