Pomplamoose covers Lady Gaga's Telephone APR 15 2010
Love it. Robin Sloan has previously discussed this type of "production as performance" video on Snarkmarket but Pomplamoose has started using the term "VideoSong":
This cover is a VideoSong, a new medium with 2 rules:
1. What you see is what you hear (no lip-syncing for instruments or voice).
2. If you hear it, at some point you see it (no hidden sounds).
