That is tough because it's personal and it changes, and it has to do with where you are in life when you hear it, or see it ... But for plays - Pillowman by Martin McDonagh and The Walworth Farce by Enda Walsh and Jerusalem by Jez Butterworth were all run into the street screaming in wonder good. I once saw a production of The Homecoming by Pinter at the Tricycle in London that was so heartbreaking I had to leave before it was over. Rory Kinnear did a "funny" Hamlet at the National in about 2011 and man, I loved that. All of these were in London except Walworth Farce which was in Edinburgh.
