I like a bit of folk, the more traditional Celtic and other European styles, mixed into rock, when done well. I also like some of the American Bluegrass-ish type of folk, forget what it's called at the moment...so I may like this as a one off.
TBH, I hate their poppy stuff from the 80's ( as I'm quite sure you are aware of by now
) so I may like it much better then that era.
I'll have to DL and give it an ear.
