This Austin outfit’s 2002 breakthrough album, Source Tags & Codes, and its 2005 follow-up, Worlds Apart, made up an irresistible double bill of furious art rock. On So Divided, they show off their poppier tendencies with a cover of the Guided by Voices ballad ”Gold Heart Mountain Top Queen Directory” and the Shins-esque ”Eight Day Hell.” They do, however, retain enough of their signature orchestral flourishes, grandiose choruses, and found-sound fragments to keep longtime fans satisfied.
