Years ago I bought a theremin because it seemed like a good idea.
When it arrived I was disappointed to discover it's almost as difficult to play as a violin. I experimented with gating it and triggering it with drums and then it got packed away.
Then the other day I was writing a list of ideas for the 2013 Leeton Art Deco Festival and I'd included the theremin, as it was invented in the 1920s.
Since I've been experimenting with putting different signals through different guitar pedals, I plugged in the theremin and found some pleasing sounds. Have a listen :)
