The title of The War on Drugs' latest album is "Lost in the Dream," fitting for a record - and a moment in time - that utterly enveloped front man Adam Granduciel. The band is now taking the final product on the road, including a stop at The Pabst Theater on Sunday, Sept. 21. Before then, Granduciel chatted with OnMilwaukee.com about becoming a real band on the road, the process behind the album and the inner battles that went into it.
