Guitar master Kaki King has spent the nine years since the release of her first album building a reputation as one of the greatest living composers on six strings. And with her most recent release, Glow, she may just have solidified that reputation for good. “This record I made is amazing. I’ve never said that about anything I’ve done before,” she told a crowd in Bologna, Italy, last March. And she’s right. The secret to King’s allure lies in her ability to capture emotion in her compositions. She does so masterfully on Glow, from the driving sense of urgency in album opener “Great Round Burn” to the slow, aching “No True Masterpiece Will Ever Be Complete.” Stroking, tapping, even slapping her guitar, she makes sounds come out of it most folks would never imagine possible. Her performances are both moving and arresting, the work of a master in her prime.
