Not Character, unless you want her to think DT aren't as amazing as they are. Show her some Gallery, some Projector, some Mind's i and some Haven. You might even want to throw a bit of Damage in there, but if you're going to show her all of that you might as well show her every single song on every single album. I say choose the best tracks from those four albums (which obviously includes all the tracks with female vocals, although it could mislead her into thinking there's a female singer in the band, which there unfortunately isn't) and make a compilation of them. If she likes it, show her the rest. But not Exposures.
