Fluster conductor (6)

I believe the answer is:

rattle

I believe this is a double definition.

'fluster' is the first definition.
(thesaurus)

'conductor' is the second definition.
(Rattle is an orchestra conductor)

(Other definitions for rattle that I've seen before include "Disconcert - conductor, Simon" , "worry" , "Clatter or bang" , "Child's toy; unsettle" , "American viper" .)

I've seen this clue in The Independent.
