And so Sumney's take on "Rank & File" taps into a similar fascination with the instrument that rests in our throats. His ability to multi-task while pulling it off no doubt makes the video even more impressive. By that I mean that for the average fan, who may or may not play an instrument, your mind spins watching him build both the song, paying attention to the looping rhythms and harmonies, and pouring his vocals a chosen mic. And I suppose that's why lip-syncing can make fans feel so cheated. It can seem like a missed opportunity to directly engage with your audience, to stir up a primal reaction to the sound of another human voice. Luckily, Sumney fans don't have anything to worry about quite yet.
