One interesting artist I saw was Sheila Chandra.

Born and brought up in England of an Indian background, she has combined English (or British) traditional songs with Indian influences - predominantly through "the first and ultimate instrument - the voice" {from the cover of her CD 'Weaving my Ancstors' Voices'}, and in my opinion, it works really well.

I also think the arrangemnts of Edward II (a group mentioned in other links before), combining traditional tunes with reggae could be deemed experimental.

On a more local note - Laurel McDonald is doing some very interesting stuff. Involved in the Toronto celtic scene with a group like 3 Our Tour, she has released a CD called Chroma which could probably be described has more "4AD" (sound of the label which features Dead can Dance, Cocteau Twins). It is a CD I really like though my colleagues felt it had gone a bit beyond what our folk club's audience would be used to and more suited to Toronto's other clubs.

Also, would Jan Garberek's recordings on ECM featuring traditional Scndinavean tunes be classified as experimental folk - again these are recordings I really like.
