Yes, it's cold out there. Really, incredibly, astonishingly cold.
But fear not, for you can easily and quickly warm yourself by gathering in the Domino Room with a few hundred other music fans (body heat!) and take in a show by alt-country rockers Son Volt. While it's not a punk show where you can work up a sweat, but swaying along to the sounds of Jay Farrar and company should heat you up.
The show is at 8pm and tickets are still available at the door.
Here's some video of Son Volt playing on the Austin City Limits show a few years back.
