Broadway fans know Idina Menzel as the original Maureen in "Rent," and as the definitive Elphaba in "Wicked." TV fans know her as Shelby Corcoran, the biological mother or Rachel Berry and leader of a rival show choir on "Glee," and she was also a featured player in the movie "Enchanted." What the uninitiated need to know is that Menzel has a huge, gorgeous voice that should fill the Auditorium Theatre and induce shivers up and down your spine. I saw her in Syracuse a few years back and the set included musical-theater staples and cuts off of her pop-leaning album "I Stand." It was all wonderful.
