On Saturday night, the people of San Francisco were forced to use Twitter for more than just banal one-liners about what they were eating. Microsoft hosted secret shows with N.E.R.D. and Yeasayer to celebrate the launch of their new mobile device, KIN, and the only place to find any info about the locations and times was via Twitter. Info on the events had been slowly leaking throughout the week, but the venue weren’t announced until three hours before the show. In a matter of minutes (first person showed up at 4.15pm!), tweets about the location had spread like wildfire, and the line to enter the Longshoreman’s Hall, an old stone temple of a venue that used to house Grateful Dead concerts and Ken Kesey’s Acid Tests, was down the block, wrapping around Beach Street and swelling with each new tweet.
Right before Yeasayer’s set, illuminated, of course, by the bright cell phone screens of people Tweeting and Twitpic’ing the show, we chatted with the band about their recent FADER cover story, their insane new music video, and more. Check out video footage from the show after the jump.
