Right, all the vote are now in. Paul (twice), BBM2, JWS, theambler and aristo have one vote each; AB has 2 votes and FieryJack and ixion each have 3 votes - up to me, then!
I loved ixion's but I'm going to pick FJ's @13, simply because my stumbling across the SINFONIETTA/INFESTATION anagram was the inspiration for the word set.
Infestation destroyed less grand ensemble (11)
Your prize is Janacek's Sinfonietta. You may not want to listen to all 24 minutes, but I would urge you to at least listen to the first movement - I think it's stunning.
