There are a few very valid reasons to be nervous about playing an in-store at Origami Vinyl; loading gear in up its perilous spiral staircase, the remote chance of plummeting off the loft into the crowd, Ali the Boxer dog witholding hugs in judgment of your set. (Full disclosure: I've played at Origami Records in my other life as a drummer, and received Ali hugs.)

We may never truly know why Sigur Rós frontman Jónsi pulled the ripcord on his planned acoustic record-store tour after playing Origami last month (he cited paralyzing nervousness at the set's intimacy, which was unexpected for a singer who headlines the world's biggest venues with Sigur Rós). But Origami and director Jack Schlinkert just posted two gorgeous clips from the show, each of songs from Jónsi's recent solo album, "Go." His otherworldly falsetto is pristine and betrays no trace of what he was feeling at the time, so enjoy these clips as the best evidence that a show like this actually happened, because it apparently won't happen again.
