Yes, the Theremin can sound bluesy. In case you haven’t seen this, here’s a wonderfully-done rendition of Gnarls Barkley’s Crazy, on Moog Etherwave Pro (recently discontinued, sadly, though maybe it’ll come back in some form), iZotope Trash for effects, Akai MPC1000, Moog Minimoog Voyager, and … actually, not sure about the keyboard. Got distracted by the general awesomeness. Theremin musicianship is on the rise!
Cee-lo will like it, I think. Watch to the end for an unusual Google + Wikipedia salute to the genius of Leon Theremin. (Yep, Google is your friend.)
These guys are also doing a whole Theremin video series — we’ll be watching. (Check out their full description at the YouTube page.)
