Self-Transforming Machine Elves is a techno-chillout duo from Amsterdam, and consists of Mark Poysden and Stefan Osadzinski. On stage they are backed up by a violinist and a flautist. Self-Transforming Machine Elves describe their music this way: "It's a journey. It's a trip. It starts out slowly and dreamlike. There are frightening parts. It strikes deep. Then the beat starts. After a while it gets scary again. But not for long. At that point we invite you to dance. We have violin, flute and trumpets. We hope you like it. We are the Self-Transforming Machine Elves."
