Cristo Redentor from Dedication by Jim Hanks
This classic Duke Pearson tune has been done a zillion times probably most famously by Donald Byrd originally and more recently by Charlie Musselwhite. I can't say that I've improved on the trumpet or harp work by those giants, but I'd be surprised if there's another version using the theremin so that ought to count for something. ;-)
I like many styles of music but most of my own productions tend towards jazz with electronic elements. I play the Akai EWI4000s electric wind instrument, ukuleles, guileles, NAF, whistle, recorders, harmonicas, and various software instruments on Windows and iOS.
