Recent performance behind large stand (7)
I believe the answer is:
lectern
'stand' is the definition.
(lectern is a kind of stand)
'recent performance behind large' is the wordplay.
'performance' indicates an anagram.
'behind' means one lot of letters go next to another.
'large' becomes 'L' (eg in clothes sizes).
'recent' is an anagram of 'ectern'.
'ectern' after 'l' is 'LECTERN'.
(Other definitions for lectern that I've seen before include "Orator's stand" , "From which speaker delivers" , "Speaking stand" , "Stand with sloping top to hold reading material" , "Slanted stand for a book" .)
