Every year, around now, you can spend a white night in Paris with hundreds of activities (something for everyone) taking place all night and until the wee hours of the morning. It’s called La nuit blanche. Typically, there will be a lot of music, street and theatre perfromances all over the city and… a lot of it is open to all and free! Karlheinz Stockhausen’s Helikopter-Streichquartett will be performed this year. More info (in French) here -> Monnaie de Paris.
