Thanks barretter and A1Philosopher for your replies. You are of course correct. I had the middle composer on the 14th row wrong.
The clue is 'Infection lacks salve initially'(3). My solution was ILS. I checked and found from Wikipedia:
Illian Walker, better known as Ils or iLS, is an English musician.
I thought this was the answer.
Having solved the third clue in 5 down I am confident that the composer is Japanese. Could some kind soul know help me the parse the clue. What is the infection?
Tomorrow is another day and I'll move on to the next stages
Thanks again
