New Rock Band Unplugged footage is chopping suey

We've already seen a trailer for Harmonix's portable rock star simulator Rock Band Unplugged, but if you want to see gameplay footage of a full playthrough of one of the title's tracks, consider your desire fulfilled. YouTuber Shadowneji02 somehow managed to get his hands on the game, and uploaded his performance of System of a Down's "Chop Suey." We've got said performance posted after the jump -- it might be a tad NSFW, as the player's band is puzzlingly composed of skimpily dressed femme-rockers. Creepy.

The video further enforces the feeling that Harmonix's debut title Frequency should feel very, very flattered by the upcoming PSP Rock Band adaptation. It also makes it that much more difficult for us to wait for this bad boy to hit store shelves June 9.
