If this has been asked before, search couldn't find it. I've had the opportunity to see a couple of shows recently, which is out of the ordinary because musicians don't come through my current location very often. So it got me thinking.
Mine is, by far, Titus Andronicus at Emo's Austin, my favorite venue of all time. I'm pretty damn sure it was this show, actually. I think my hands are in there a couple times. Watching that brings me right back. Wow. Here's the opener. That was the best crowd I've had the privilege of being a part of, which was completely par for the course at Emo's before it closed/moved.
Titus, aside from being utterly insane, puts on a fantastic show, walking the line between faithful renditions for familiarity and crazy improvs for kicks. They love what they do and it shows. Their particular brand of indie punk translates so well live -- we went from dancing and screaming to spellbound rapture in a heartbeat, depending on what they were playing.
