Philadelphia’s War on Drugs return to the National to support its still-fresh major label debut, “A Deeper Understanding,” an album that sees the band continuing to hone its unlikely synthesis of kraut rock, shoe gaze, and heartland boomer rock. Though the broader, polished album could potentially alienate fans of the band’s earlier work, traces of band leader and notorious perfectionist Adam Granduciel’s affection for arena rock can be detected as early as the band’s 2008 debut, “Wagonwheel Blues.” For anyone who believes that Mark Knopfler and Kraftwerk have more in common than just their relative placement in an iTunes folder, attendance is mandatory. XL102 Miracle on Broad Street presents the War on Drugs and the Building on Thursday, Dec. 14, at 7:30 p.m. $24.50-$28. thenationalva.com — James Toth
