Wolf Trap Opera's 'Carmen': This production could use a little more of the original

With its brawling, cigarette-smoking women and the on-stage murder of its hot-tempered heroine, Bizet's "Carmen" pushed the envelope for Parisian audiences when it premiered in 1875. And in a way, Wolf Trap Opera pushed a couple of envelopes of its own Friday, outdoors at the Filene Center, in a one-night-only performance of Bizet's classic that touted 21st-century technology in a production that sounded better than it looked.
