Since her multiple-Grammy-garnering 2018 LP, By the Way, I Forgive You, Brandi Carlile has written an autobiography, created the female supergroup the Highwomen, and celebrated Joni Mitchell and Tanya Tucker to a new generation, producing the latter’s Grammy-winning comeback. Still, last year’s seventh LP, In These Silent Days, delivers the highlight of the past five years, weaving touches of Mitchell and Tucker into Carlile’s powerfully torching ballads and deeply personal narratives facing off with doubt and defiance. Electro-pop quintet Lucius opens, grooving new Second Nature, before taping their Austin City Limits debut on Sunday.
