The Aberration theme from Shaped Pixels of Vancouver, Canada is minimalist and elegant on the outside but has an 'everything but the kitchen sink' approach on the inside. The theme is billed as a Photographic and Personal Blogging theme. It could just as easily be the backbone for a business or magazine site.
This theme is one of the most configurable themes I have worked with. While most themes require some level of under the hood tweaks to get the look and functionality that is desired, this theme has so many choices in the customizer and widget space that it is likely the desired look will just require figuring out which 'button' to push.
