Under a microscope, a rock becomes a world in its own right. Its crystalline gestures, made over eons, hold records of change that echo patterns found everywhere: in rivers and lightning, in tree rings and coastlines, in the way a flock turns and a city grows. The eye gets lost in the stone, and the mind starts to rhyme. Here, I share what I find, one stone at a time, and the music I hear in each one.

I’m Eric Oberthaler. Most people call me eO. You can reply to any email; replies come straight to me.
