I first heard a Theremin used in rock music by Rev. Paul Jackson of The Uptones. The instrument was easy to record, but you looked lame playing it. Not much later I saw Aron Mardo not looking lame using this all electronic instrument in an inspired performance with his brother in their band Mardo. I fell in love with the unlimited possibilities of this electronic instrument. As I looked further, into this instrument’s roots, I also found some Public Domain music using all electronic music instruments. As you guessed, it wasn’t made before 1925, it was made in 1960 in a no-copyright-law USSR! This video features Russian Thereminist Konstantin Kovalsky, performing with Vyacheslav Mescherin’s ensemble of electro-musical instruments. I find this a mind-boggling display of electronic instruments. Konstantin makes the theremin sound almost human in his solo. I found this video fascinating.
