Composer unexpectedly paroled in his home (8,3)

I believe the answer is:

bachelor pad

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

'his home' is the definition.
The definition suggests a singular noun which matches the answer.

'composer unexpectedly paroled' is the wordplay.
'composer' becomes 'bach' (Johann Sebastian Bach).
'unexpectedly' is an anagram indicator.
'paroled' anagrammed gives 'elorpad'.
'bach'+'elorpad'='BACHELOR PAD'

'in' is the link.

Can you help me to learn more?
