Trumpet music is meat and drink to the enthusiast! (7)
I believe the answer is:
fanfare
'trumpet' is the definition.
(thesaurus)
'drink to the enthusiast' is the wordplay.
'drink' becomes 'fare' (I can't explain this - if you can you should give a lot more credence to this answer).
'to' means one lot of letters go next to another (I've seen this in other clues).
'the enthusiast' becomes 'fan' (fan is a kind of enthusiast).
'fare' after 'fan' is 'FANFARE'.
'music is meat and' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for fanfare that I've seen before include "Ostentatious display" , "Flourish played at military Ceremonial" , "Flourish of trumpets" , "Enthusiastic display" , "A ceremonial blast of trumpets" .)
