Best of everything and with the most quickly approaching end date was Cheek By Jowl's Ubu Roi at the Barbican. It was anarchically wrong and just awfully gleeful; I've never seen greed portrayed so unsympathetically, and I've never seen a toilet brush used as a scepter before.
Most important is probably The Arrest of Ai Wei Wei at Hampstead Theater. I think it may have actually been a boring evening, as mostly we watched Ai Wei Wei sit in a room and be stared at; but I think it had a powerful political intention behind it that turned the "performance" into a political statement. Recommended if you're interested in China, modern art, or human rights.
I was disappointed by two promenades; The Trial by Retz and The Salon Project. God knows I'm dying for friends and conversation, but the Salon Project merely gave me some clothes and champagne; meanwhile The Trial was emotionally uninvolving.
Finally I whipped out a review of some modern ballets by Nacho Duato the Mikhailovsky performed during their Easter visit to London. My ballet reviews don't get read much but I do want to keep working to become better at describing this kind of art, so this review was really for me.
