How do your emotions color your perceptions of a performance?

Something I said in my comments on Contemporary Baroque got me thinking: "One might think that the fast movement from Summer (Four Seasons) was overused, but Mercury Baroque's performance of it combined with my own jumbled feelings that evening made it fresh and pertinent." What would my reaction have been if I'd been in a different mood? This is a question for you, dear readers (is anyone out there?); post a comment describing any time a performance touched upon some current theme in your life. For me it was Vivaldi's aural depiction of the fury of a summer thunderstorm that matched my own swirling, strong emotions. The dancers seemed the perfect visual realization of the music, their energy and momentum ranging widely yet governed by well defined laws. A slightly different example of altered perception: In college, I saw a performance of James Joyce's Finnegans Wake by Pilobolus. (By the way, Pilobolus will be here April 29!) There was a scene where, if I remember correctly, a woman was attached to a pulley up above by a rope, and the man dancing with her manipulated her up and down using the rope, their movements slow and gentle. It struck me as a beautiful expression of someone supporting and nurturing someone they love. I discovered later it was meant to represent something darker and more violent (I'll have to dig up the paper I wrote to find out what). But without being familiar with the story of Finnegans Wake, I took away something entirely different than what the choreographer intended.
