I have always admired Theramins and people who can play them. I have had a go, but they are a bitch to play in tune. It takes incredible sense of pitch and subtle nuances of touch. One day I will get one and learn it's mystical art.
On an earlier post I had a cool live video of Gnarls Barkley and their hot string section 'The G Strings' and to follow that up and bring this little blurb full circle, here is 'Crazy' being played on Theramins, brilliantly.
