It was a truly nutcase “Snow Maiden” at the Mariinsky last night, Rimsky-Korsakov’s operatic masterpiece of returning spring, reimagined via copius amounts of LSD in a surreal world of fairy tale meets Sacre Du Printemps via liberal helpings of marijuana. What were the set designers on? Shades of Chinese New Year as well as our heroine eventually melts and the sun is free to shine and usher in a very late spring. Madcap, but fun.
