Ryan Lott, aka Son Lux, is probably best known for his work with Sisyphus — the strange rap project in which he collaborates with Sufjan Stevens and Serengeti — but like his Sisyphus bandmates, Lott moves all around the style spectrum. Recently, Lott composed a piano piece for a Gillette ad, in which he also appears. In the ad, Lott plays a keyboard that’s rigged to 88 razors, which then hit the keys of the piano with their handles (which then would trigger the hammers to hit the strings, in case you were wondering how pianos work without the addition of Gillette razors). It’s a kind of ridiculous concept, but still … watching him play that weird contraption is pretty cool. Watch it below.
