Neurogenesis expands the sound of modular analog and digital synthesizers into a bright and dynamic landscape, layered with shimmering kaleidoscopic microtonal patterns, pulsating, vibrating and evolving. Is this the sound of neurons growing?

I started this album in Spring of 2019, inspired by a lucid dream that also spawned a cube-shaped painting. Vibrating and microtonal, shimmery and crystalline, Neurogenesis expresses optimism about the potential for human consciousness.  At the start of pandemic lockdown in March, I stopped working on Neurogenesis to record “Offering to the Morning Fog” because listeners were asking for something very calm. I got back to work on Neurogenesis in June, and finished in late October. I had specific ideas for the artwork, and John Bergin did his magic again, to help me realize a visual language beyond my imagination. 

From the very start, I planned Neurogenesis to come out on LP along with CD and download. (The LP has different artwork and liner notes from the CD, and comes on clear vinyl.) Unfortunately, vinyl pressing plants are running very slow, so the LP will not be available until March. The CDs should be here in mid-December, so I decided to release it now for Bandcamp and CD Pre-orders. CDs should ship before Christmas if all goes well. I do not plan to offer it to streaming services like Spotify or Pandora. 

March 28, 2019: Dreaming of mathematics. I am looking at a cube, covered in curving lines that snake around the corners and map a multidimensional equation. Someone explains to me that the derivatives of these curves (like velocity is to position, and acceleration is to velocity) represent the edge sensors of an organism, which detect contrast and change in the environment at a fundamental pre-conscious level. We have edge detectors like this in our retina, which send efficiently coded signals to our brain to help us see details in the world more quickly. 

As I mentally project this calculus onto the curves, I watch as they grow projections reaching back towards me, cilia growing out of an organism, whiskers, or fungal mats underground. This moment feels like the “sharpen” filter in a photo editor, heightening the contrast of everything around me. This helps me perceive that the derivative of my perception of time is the pinprick of the moment, an edge detector of quantum consciousness, the “bija” or particle of thought. Take the derivative of what seems to be linear perception, define its instantaneous curvature, exponentially sharpen it to better sense the verb that is time.

When I woke up from this dream, my mind was filled with an intuition of curves and power functions, like measuring waveforms of energy and quickly sensing their qualities at this precise moment. The feeling faded after a few minutes, and my day proceeded as normal, but with an echo of this beautiful perception. A remnant image hovered in my periphery, a sentient cube with textures and lines, floating in front of me with a saturated background that merged into its corners, making it seem curved and organic.
