I've been to the Bataclan five years ago, Low was playing there as support act for Mercury Rev. Here's my
recording of Low's set. To be honest I don't recall much anymore about how the venue was like. But it had very good sound. I've more fond memories about the Thurston Moore night a couple days later at La Villette who was headlining for Half Japanese and Glenn Branca.
I'm really shocked about what has happened, and seeing the video of people running out of the back exit of the building. A Dutch guy who was at the concert had been hiding under a pile of dead bodies for some time.
