Member of the orchestra who's a bit too boisterous? (6)

I believe the answer is:
oboist
'member of the orchestra' is the definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'a bit too boisterous?' is the wordplay.
'a bit' indicates the answer is hidden within the clue (the answer is formed by a bit of the clue).
'OBOIST' can be found hidden inside 'too boisterous'.
'who's' acts as a link.
Can you help me to learn more?
(Other definitions for oboist that I've seen before include "Wind player" , "Do I boost the musician?" , "Instrumentalist" , "Player of woodwind instrument of treble pitch" , "Musician who plays woodwind of treble pitch" .)
