From the man who created the Marble Machine, Wintergatan's Martin Molin brings us a unique rendition of Dr. Wily's Mega Man 2 theme played on the "Modulin". The Modulin is a home-made device, a mix of a modular synthesizer and a violin created by Molin. It sounds a bit like a souped-up, high-tech theremin.
Have a listen, if you'd be so inclined! (Thanks for the tip, Niroth!)
