New singers making entrance (7)
I believe the answer is:
ingress
'entrance' is the definition.
('ingress' can be a synonym of 'entrance')
'new singers' is the wordplay.
'new' is an anagram indicator.
'singers' is an anagram of 'INGRESS'.
'making' is the link.
(Other definitions for ingress that I've seen before include "Singers provide a means of entry" , "The act of entering" , "Entrance, access" , "Means of access" , "Way in" .)
