Comparisons between "Celtic Woman" and "The Dixie Chicks" are fairly pointless. One is a concert series, backed by promoters and probably co-ordinated by a huge production staff & the other is a group of "Free Thinkers" who have proven, especially in recent years, that they are their own drivers.
Regardless of the fact that both shows are extremely well produced and absolutely saturated with talent, they are dissimilar in so many ways.
I scanned through one of Big Mick's submissions, further up, and find myself in the most awkward position of actually agreeing with him. Hmmm!
Keep it up Mick and I might take your name off the list.
Now; Alison Krauss! No flash, no fan fair, just raw perfection.
That's Folk!
