World/New Age/Celtic/Folk/etc. artist Loreena McKennit will be appearing at this year's Tollwood as part of her German tour.
Not my personal taste, but I'm quite sure she'll have some fans on TT, I remembered her name more for her libel case to be honest.
Anyway, tickets not yet available but shortly - ordering directly via the Tollwood hotline is the cheapest method to get yours.
