Less than two weeks after making her Grand Ole Opry debut on April 25, Bella White comes to Medford for a performance at The Porch. She’ll be joined by special guest Rosie Porter, a frequent Porch performer with the Neon Moons. A 22-year-old singer/songwriter originally from Calgary, Alberta, Canada, White has a one-of-a-kind musical talent: a finespun breed of country/folk both fresh in perspective and wholly steeped in bluegrass tradition. She’ll be sure to play some cuts from both her debut album “Just Like Leaving,” which she recorded as a teen-ager, and her sophomore album, “Among Other Things,” which was released on April 21. Tickets are $15 through Eventbrite.
