With the release of the seventh and final book at midnight this Saturday, the Harry Potter series will soon be complete, and the future of “wizard rock”--a subgenre of indie rock inspired by J.K. Rowling’s fictional world--is uncertain. Will wizard rock pioneers (and 2007 Philadelphia Book Festival performers) Harry and the Potters --as well as nearly 200 similarly inspired acts around the world--maintain their cult followings after their source material has been brought to a conclusion? In the past week both Salon and National Public Radio’s Day to Day have produced pieces considering the fate of wizard rock, each ultimately postulating that the genre is currently in the middle of its crescendo moment. If this turns out to be the case, make sure you take some time to revel in the fun before the moment passes. Come down to the Central Library on Friday, August 10 at 12:00 p.m. and enjoy sets by wizard rockers the Remus Lupins , the Whomping Willows , and the Moaning Myrtles . And for die-hard enthusiasts, the Marauders will be playing a set Friday evening at Big Blue Marble Bookstore in Mt. Airy as part of a full evening of events celebrating the release of Harry Potter and the Deathly Hallows.
