Re-working your tunes with an orchestra has been done several times (I think Metallica started that craze, didn't they?), doing a country album has been done countless times, doing a standards album has been done to death.
All of those things seem kind of gimmicky and overdone at this point... and Stevie's already criticized enough by her fans for doing things that are "rote".
Me, I'm not looking for the reinvention of the wheel, or for Stevie to "do like so-and-so did"... I just want a new STEVIE NICKS album in the classic vein.
