@jackie: Depends on what sort of fantasy. Some pieces need Celtic stuff, some need symphonic metal. Some need David Bowie or Queen (those are always fun)
I have been a fan of Enya, Clanned, The Corrs and expecially the Celtic Women! If you want a real treat, listen to Lisa Kelly's version of the theme of The Gladiator! It is mesmorizing and haunting! Good on ya Lassie!
I find that when writing anything supposedly fantasy, listing to Celtic Woman is inspirational. Just had to leave my comments. If and when Brynna runs across this comment she is going to laugh.
An excellent group for aspiring writers.
