You have to react to what's around you in the moment, whatever the music is. Just think of it as some place you have to enter and you need to find the key.
Each organism, no matter how simple or complex, has around it a sacred bubble of space, a bit of mobile territoriality which only a few other organisms are allowed to penetrate and then only for short periods of time.
I have friends who remember seeing fish hauled onto a boat's deck and beaten to death.
