I've never been all too big on Apple, but I've gained some respect for the gene pool she derived from, after discovering her sister Maude Maggart. She's a cabaret phenomenon, so I figured I'd point her out for those who hadn't already heard of her either. Her music has a very classic and, well, cabaret feel to it, so I find it easy to fall in love with.
Unfortunately, there aren't any videos online of her actual on-stage productions and performances, but here is a video of her laying down a couple of tracks in the studio.
