Lucy Dacus is done thinking small. Two years after her 2016 debut, No Burden, won her unanimous acclaim as one of rock’s most promising new voices, Dacus returns with Historian, a remarkably assured 10-track statement of intent. “This is the album I needed to make,” says Dacus, who views Historian as her definitive statement as a songwriter and musician. “Everything after this is a bonus.”Dacus and her band recorded the album in Nashville last March, re-teaming with No Burden producer Collin Pastore, and mixed it a few months later with A-list studio wizard John Congleton. The sound they created, with substantial input from multi-instrumentalist and live guitarist Jacob Blizard, is far richer and fuller than the debut — an outward flowering of dynamic, living, breathing rock and roll. Dacus’ remarkable sense of melody and composition are the driving force throughout, giving Historian the immersive feel of an album made by an artist in full command of her powers.
