Will the first iteration of tech startup MAGIC LEAP's much-anticipated mixed-reality goggles be a trippy 3-D SIGUR RÓS video? Quite possibly, based on this mind-bending demo PITCHFORK's MARC HOGAN got from the FLORIDA company. Reading Hogan's description of manipulating jellyfish-like figures that floated in space around him and altering the music as he did, my first reaction was "cool!," my second was, could you maybe have found a less-on-the-nose band than Sigur Rós for this, and my third, as REDEF's resident Luddite, was: Music? Really? Is that the most interesting first-use case for this tech? And then I checked my cynicism. Maybe it's specifically because music isn't a visual medium, and yet still has the power to envelop your senses, that it's the perfect, most malleable and most open-ended introduction to this sci-fi reality. I want to experience this. VERGE read the same description and had some more prosaic questions, like, why hasn't Magic Leap "shown us an app store, an operating system, or any kind of hardware"? Fair. But I'll leave the biz-dev questions to the biz-dev experts. I just need to be amazed... K-pop fans are mourning the death of KIM JONG-HYUN, better known by the single name JONGHYUN, who was a ridiculously talented triple-threat as a member of the long-running boy band SHINEE, as a confessional synth-pop solo artist and writer/producer for other acts. As a singer, he had "this belt that just sort of gives you chills automatically," K-pop expert JEFF BENJAMIN told the WASHINGTON POST. He was 27 and his death is believed to be a suicide, a possible reflection of both SOUTH KOREA's unusually high suicide rate and a record industry that's uber-competitive and controlling of its own artists. His final INSTAGRAM post, translated in the Washington Post link above, is heartbreaking; his final solo music aches with both love and melancholy. RIP... This song had never been in the BILLBOARD top 10 until this week, which is mind-boggling and sad and maybe that's what people mean when they say there's a war on CHRISTMAS. Thank GOD the war is now over... Everyone owes TOM DELONGE an apology... A new champion for jazz on CAPITOL HILL... The NBA owner and the jailed rapper... The missing tattoos are problematic (#AsIsEverythingElse)... RIP BOB SEIDEMANN.
