Since yesterday's (Feb. 16) unveiling of the official schedule for the 2015 edition the SXSW Music Festival, we've already started building out our itinerary. And today, SXSW has announced a new show that will absolutely find its way onto our calendar: Brandi Carlile and the Twins will be performing an extremely intimate concert on Wednesday, March 18, at the Central Presbyterian Church on 8th Street in Austin.

Since her early years as a budding singer-songwriter, Carlile has become one of our favorites in the alt-country and Americana scene. Needless to say, we can't wait to get our hands on her fifth full-length album, The Firewatcher's Daughterset for release a couple of weeks before SXSW on March 3 via ATO Records.

Carlile's set at Central Presbyterian will likely be one of the most memorable of the week, considering she and Tim and Phil Hanseroth are performing it unplugged. And when we say "unplugged," we mean they won't be plugging into anything. There will be no microphones, no amplifiers -- totally, 100-percent acoustic.

(There's a reason her current tour is dubbed the Pin Drop Tour.)

Doors open at 7:30PM CT and Carlile is scheduled to start around 11:00PM. There will be two opening acts, though they have yet to be announced.

Those who have wristbands or are registered for SXSW Music will have access to the show free of charge. If you're in the area but not attending SXSW, there may be a handful of tickets available the day of at the church.
