Musical performer realistic about Shostakovich's Fifth (10)

I believe the answer is:

recitalist

I'm a little stuck... Click here to teach me more about this clue!

'musical performer' is the definition.
'recitalist' can be an answer for 'performer' (recitalist is a kind of performer). I am not sure about the 'musical' bit.

'realistic about shostakovich's fifth' is the wordplay.
'about' indicates anagramming the letters.
'shostakovich's fifth' becomes 't' (5th letter of 'shostakovich').
'realistic' with letters rearranged gives 'recitalis'.
'recitalis'+'t'='RECITALIST'

Can you help me to learn more?
