One Knoxville native is excited to perform for her hometown community and support a good cause Friday evening. Heidi Feldman, a successful musician who spent several years as a touring performer before coming back to Iowa, will be performing in her first show in a long time in order to give back to the community and promote the arts in Marion County. Unplugged Diva! is a laid back, informal, acoustic concert featuring Feldman and pianist John Mattingly of Newton and will take place at Peace Tree Brewery Friday at 7:30pm. Tickets are $7 at the door and all proceeds will go directly to the Red Rock Arts Alliance who will use the money to bring great arts and culture to Marion County.
