Greetings - Thanks for Visiting with us tonight... 

So, the Answer is:  The instrument you here being played is the Theremin.  ( modified a bit and played close-up )  

The Theremin is the first electric/electronic musical instrument.  Still a Mystery -  Less than1% of people have heard it live. 

You play it by ' waving your hands ' around antennas attached to the body of the instrument with circuits inside.

 The instrument is about a hundred years old from its concept with the first few weird sounds coming from " the Ether ". 

 They didn't know what it was; along with Edison's Bells, these early dudes were getting sounds from nothing ?

From the the air, outer space, the ether, heaven, maybe other dimensions. 

 Yeah it's a magnetic field activity - but where's the sound coming from they first thought - And it sounded mysterious too!

Meanwhile -  vaudeville, rag-time, boogie-woogie, western swing, blues, and jass too outside the laboratory late at night! 

You had traveling roadshows, jukes, clubs, carnivals, theatres, opries - all kinds of new music  - things were happening! 

As we know it, the Theremin was actually played in classic symphony arrangements and established entertainment. 

But, You wonder if someone, somewhere, got ahold of a theremin and played something else cool,  - it's a mystery 

Hawaiian Guitar, Bottle-Neck, Knife-Edge Slide; DiddlyBows; even Saws were played with some sounds resembling a Theremin  

The Theremin (or the Aetherphone) was developed by Leon Theremin (1896 - 1993 ) and got patented in 1928. 

My name is Mackie; I'm on to create a more modern method of playing the theremin with some patent-pending Mods.

My day-work is in engineering; Then I'm into my rhythm & blues experimentation.  I love to listen and try to play.

 Practicing with backing tracks and favorite songs, I'm after a range of sounds and styles from sweet,  emotional,  gritty,  honky-  tonk , boogie and bluezer blues, ultra-blues, keep playing the blues blues;  Unknown unique underground - no problem

A blues novelty - this is some magnetic mystery music  carried from the early days of science (and modern entertainment )
