The bell trees of "In Bosky Jangle" were made for an exhibit at the Bolinas Museum in 2015. In the years since they've been in residence in several other locations, including several years at Bridge Storage, Arts and Events. They're now in retirement in an out-of-the-way woodsy location, getting rustier with each passing season.

And by the way! Bart has recently released an album of his music, made primarily on instruments he's made. It's called Audiorium, and it's available through the usual download and streaming services.
