If you look up Dolly Parton on the internet, you’re sure to hit her page on Wikipedia, that bastion of collective knowledge encouraging input from every would-be expert. So what if the site lists “fingernails” as one of many musical instruments Dolly plays best? The lady could grind her teeth, and it would be music to our ears. When she plays the BOK Center on Oct. 8, fans are more likely to hear music from her new album, Better Day, which debuted at No. 11 on the country album music charts. The mega-star – who has crossed into film, television, entertainment tourism (including her Dollywood theme park) and other business ventures – shows she remains true to those east Tennessee roots with a show of new material straight out of sweet ol’ Pigeon Forge. www.bokcenter.com
