Often at concerts and local shows, the lull between bands means that you'll see a bunch of faces lit by the glow of their smartphones as they peck out texts, hunt for Tinder matches or read their Twitter feeds. But at the Granada, sometimes they're all lit by ... well, a Twitter feed. At least it's a somewhat more communal feed, as a big screen displays the sometimes funny, sometimes ridiculous and sometimes offensive tweets from patrons to the venue's account. (Though one doesn't have to be present to get a tweet up there, references to the show make it clear that generally participants are indeed in the building.) Sometimes it's the most entertaining part of the show: People at indie-rock shows are as good at issuing snarky one-liners as the bands are at staring at their feet.
