Promoted enthusiastically — as was Louis Armstrong's music? (9)

'promoted enthusiastically' is the definition.
The answer and definition can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?

'was louis armstrong's music?' is the wordplay.
I cannot really understand how this works, but
'music?' could be 'te' and 'te' is found in the answer.
The remaining letters 'trumped' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

'as' is the link.
