If you sit close enough to the front of the theater for 'A Streetcar Named Desire' at the Brooklyn Academy of Music, you can see Paul Mescal spit and sweat as he stalks the stage as Stanley Kowalski, an artist doing his work in real time and space. It had been a while since I'd seen live theater when I went to see 'Streetcar' a few weeks ago, and I found myself in awe of the very liveness of it. I've grown so accustomed to experiencing culture through screens that I forgot how exciting it is to be in the room where the art is happening, to witness the effort and passion and bodily exertion that go into it.
