The anonymous YouTube viral phenomenon iamamiwhoami has uploaded its sixth teaser video: YouTube has been permeated with these cryptic viral videos over the last couple of months. According to Pitchfork, iamamiwhoami "first started uploading mysterious clips (and e-mailing us and many other websites about them) in December." Each video features a very brief array of musical delights: an amalgamation of synths, some rather 'pretty' electronica, and industrial beats, breathy vocals... experimental but not too alienating, either. What's more intriguing, however, is the videos to accompany each snippet. They're lavishly produced, suggestive, ethereal, maternal. We see an obscured blonde woodland dweller with a painted face and giant lashes, writhing in muddy fluids, licking a pretty vaginal-looking tree until it excretes, and er, puppies frolicking in the snow. Whoever is behind this obviously knows how to raise an eyebrow and has a fair budget and a creative mind to work with. The videos are almost like Matthew Barney collaborating with Fever Ray but for a pop music video a la Lady Gaga. Each one also features a simple illustration of an animal: whale, bee, owl, goat, llama, and now monkey. With an accompanying link in the video description, to a video of that creature. The title of each clip is a simple numerical code, the latest of which spells “Welcome Home”, and they are tagged with descriptive words such as foetus, nourish, cortex, sap, disciple, and wood. Are they clues? Your guess is as good as mine. So far allegations of who the artist is seem slightly ridiculous: Christina Aguilera (whose camp has denied it), Goldfrapp, MGMT, and The Knife. Given the Scandinavian nature of the videos, I'd see Logic into some people suggesting the Knife, however there is nothing on the new Knife record that bears a musical resemblance, and Karin is too low-key for this kinda shit. Lady Gaga is another popular hunch, but that seems too obvious, right? Either way, you gotta admit it's a good viral marketing campaign - especially if it is a new artist (that's where I'm putting my hypothetical money). With over 3000 subscribers on YouTube with barely a few minutes of material, they must be worth keeping an eye on, right?
