The music Ella Williams makes as Squirrel Flower has always communicated a strong sense of place. Her self-released debut EP, 2015’s early winter songs from middle america, was written during her first year living in Iowa, where the winter months make those of her hometown, Boston, seem quaint by comparison. Since that first offering, Squirrel Flower amassed a fanbase beyond the Boston DIY scene and has released two more EPs and two full-lengths. The most recent, Planet (i), was laden with climate anxiety, while the subsequent Planet EP marked an important turning point in Williams’ prolific career; the collection of demos was the first self-produced material she’d released in some time. With a renewed confidence as a producer, she helmed Tomorrow’s Fire at Drop of Sun Studios in Asheville alongside storied engineer Alex Farrar (Wednesday, Indigo de Souza, Snail Mail). Williams and Farrar tracked many of the instruments, building the songs together during the first week, and then assembled a studio band that included Matt McCaughan (Bon Iver), Seth Kauffman (Angel Olsen band), MJ Lenderman, and Dave Hartley (The War on Drugs) lending their contributions.
