Drunk actress grabs thrilling hour entertaining male musical director (6,6)

'musical director' is the definition.
(I know that chorus master is a type of choir director)

'drunk actress grabs thrilling hour entertaining male' is the wordplay.
I cannot really see how this works, but
an anagram of 'hour' is 'horu' which is located in the answer.
'male' could be 'm' (common abbreviation) and 'm' is found within the answer.
an anagram of 'actress' is 'csaster' which is located in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
