Two weeks ago, Philip Mann debuted as the music director for the Arkansas Symphony Orchestra to great acclaim. After kicking his tenure off with the likes of Bernstein and Dvorak, Mann steers the symphony into more lighthearted fare with this season's debut of the Pops Live! series, Halloween Spookfest. To get into the spirit, the orchestra will be dressed in costume (maybe Mann will be a zombie conductor); it encourages the audience to do the same. Either way, the concert's likely to get you in the Halloween spirit. It features some of the scariest songs ever, including Saint-Saens' Danse Macabre and Bernard Herrmann's "The Murderer" from "Psycho." As well as more playful fare: the themes from "Batman" and "The Addams Family" and selections from John Williams' scores for "Harry Potter and the Sorcerer's Stone," "E.T." and "Star Wars." The ASO reprises the performance on Sunday at 3 p.m.; same place and price, though students, grades K-12, can go for free if accompanied by a paid adult as part of the ASO's new Entergy ticket program on Sunday.
