Andrew Masters is an artist and a builder of kalimbas. He uses recycled materials, and adds a touch of his own art to his highly original kalimbas. I found his sardine can treble kalimba to be quite good. I recommend the 11-note bass kalimba, but I did not like the 15-note bass kalimba as well.
Here is a short animation that Andrew made with his kalimba music in the background.
