Record in auditorium for composer (5)
I believe the answer is:
liszt
'composer' is the definition.
(Franz Liszt)
'record in auditorium' is the wordplay.
'record' becomes 'list' (list is a type of record).
'in auditorium' indicates a 'sounds like' (homophone) clue (as the word might sound to an audience).
'list' is a homophone of 'LISZT'.
'for' is the link.
(Other definitions for liszt that I've seen before include "Hungarian composer,d. 1886" , "Hungarian piano virtuoso, d. 1886" , "classical composer" , "Franz -, Hung. pianist" , "music writer" .)
