I’ve been performing more and more improv based material, and am always looking for ways to make it a more immersive experience for the audience. For the most part, I normally perform pieces that are around 25-30 minutes long, and I’m looking for some kind of natural time device that the audience and I can both see, and that’s cooler than just a timer on my phone.
I was inspired by seeing Anthony Braxton—his Ghost Trance pieces were typically an hour, and he would always start the set by turning over a gigantic sand hour glass! I also really like @marcus_fischer 's use of a levitating tape reel----not necessarily a time keeper, but definitely an object that can help bring about a trance if you look at it long enough.
Does anyone know of any cool esoteric time keepers?
