This video captures a tasteful tribute to Michael Jackson, a theremin cover of Jackson's Ben.
The song is performed on a customized Moog Etherwave Pro by YouTuber copperleaves. It's an expressive performance that honors Jackson's legacy, while celebrating "Michael's amazing but very troubled life."
Many more theremin performances are available at copperleaves' YouTube site.
It looks kinda like SMR but it is definitely not!
