A white-haired lady wanders Richard Neutra’s landmark midcentury house in Silver Lake at night, when she suddenly encounters a mountain lion calmly purring — and a grand piano in the room begins to play, on its own, Philip Glass’ “Mad Rush.”

He had Steinway program a player piano to perform “Mad Rush” with Glass pounding playing style, and he had his roaming camera observe the big cat’s response to the music.

In case you’ve blocked it out of your memory, the game is as it sounds: a mad rush to dodge a rubber ball being hurled at you by a member of the opposing team.

“When you’ve directed something or in something, there’s always this mad rush of adrenaline. I had that, but I had a real quiet feeling that whatever happened, this is the show I wanted to be seeing. This is how I wanted it.”

As you can see, there's a bit of a mad rush as photographers swoop in to take his picture.
