Chris Willman Senior Music Writer and Chief Music Critic Allison Russell, Brandi Carlile and Billy Strings were among the winners Wednesday night at the Americana Honors & Awards ceremony in Nashville, where the love was spread around among the genre’s current leading lights. Six different performers prevailed in the six voted categories, with newcomer Sierra Ferrell, instrumentalist Larissa Maestro and the husband-wife duo the War and Treaty also coming up winners. The competition can be more inter-familial at the Americana Awards than at other shows, and the three leading nominees — Carlile, Russell and Yola, who had three nominations each — have been particularly tight-knit in supporting and guesting with one another. Carlile was even instrumental in helping get Russell her record deal with Fantasy Records.
