I will have to give another listen to Tori Amos.

Her 2011 Night of Hunters is worth a look : a journey into the dark heart of Irish Mytholog which manages to do it without a single note of the old Riverdance creeping in, rather she bases it all on variations of familiar classical melodies. Bizarre but affecting!    And be sure to check out her Xmas album nearer the time - Midwinter Graces (2009) - in which she gives an uplifting Tori twist to lots of familiar chestnuts, and points the way to a few unfamiliar ones. I especially like this one...
