Hannah Mohan’s new album is a first in more ways than one. Time Is a Walnut is the first solo release from the Western Massachusetts singer and songwriter, after nearly a decade fronting indie-pop band And the Kids. The album also comes amid the longest stretch Mohan has spent in one place since she left home at 16 to hop freight trains and hitchhike across North America. Making music has been at the center of Mohan’s life ever since, even as other circumstances have changed—sometimes radically. A long-term relationship crumbled in 2019. Then the pandemic arrived, bringing an end to her band. After writing a batch of new songs taking stock of her situation, Mohan asked Alex Toth of Rubblebucket and Tōth to produce them, the latest installment of a longtime friendship and occasional creative collaboration. Although Time Is a Walnut is a breakup album, don’t go in expecting tearjerkers. Mohan draws from a richer palette here, with themes of messy eroticism on the sultry “Soaked,” altered consciousness on the buzzy rocker “Heaven and Drugs," and navigating personal hells with Lady Lamb on “Hell.” Throughout, the songs showcase Mohan’s powerful voice, prismatic melodicism and distinctive lyrical sensibility as she processes major events in her life.
