Just a thought-
It's been suggested that Whitby should incorporate more modern, or "less-Trad" artists. I'd like to voice a loud disagreement.

Whitby is almost completely alone in being, essentially, an all-Trad festival. There are lots of places to hear more modern music; adding to the Whitby line-up would only dilute its unique appeal. IMO the best festivals are those that stick closest to a theme or idea or ideal--"something for everyone" generally translates into "not enough anything for anyone".

Themed festivals (like Mystic's Sea Music Festival) have been historically most successful when they stuck to their guns.
