Blood on the Wall’s musical development must have been arrested sometime during a Slanted and Enchanted–era Pavement show. Sure, indie rock has evolved past the lo-fi sensibilities and liberal employment of distortion pedals, but siblings Courtney and Brad Shanks (along with drummer Miggy Littleton) are clearly either unaware of the dance and folk elements that have since infiltrated indie rock or just refuse to acknowledge that music has been made since 1995. During the course of its three albums—the most recent being 2008’s Liferz—Blood on the Wall illustrates a comprehensive journey through its Sub Pop, Matador, and SST collections, harkening to the days before the members of Sonic Youth became parodies of themselves. Which is to say, Blood on the Wall’s output may be a musical regression, but at least it’s a welcome one. Blood on the Wall performs with Cause Co-Motion! at 9 p.m. at DC9, 1940 9th St. NW. $10.
