If you saw the new Chevy Malibu commercial that premiered during the World Series you heard Charlotte's Matrimony. The group's track "Obey Your Guns" (which you can hear in the above music video) is available on iTunes
here.
The band reports it has completed recording its major label debut, which should be out next Spring. You can catch them live before then as they'll be hitting the road in anticipation. You can follow their antics on Twitter
here.
