After meeting as students at the esteemed Berklee College of Music in 2018, Guy, raised in the thick of Richmond's Celtic and old-time music scene, and Simpson, who cut her teeth on radio harmonies in the backseat of her mom's car, quickly bonded and created something fierce together. They kick off every set with explosive double banjo fury, their lightning-fast playing and razor-sharp harmonies equally informed by punk basements in Allston and centuries-old ballads. Sweet Petunia channels that musical intensity into Foggy Mountain Mental Breakdown (out March 13, 2026 on Righteous Babe Records), a collection of songs born from a period of growing pains, reflecting on breakups, outgrown friendships, destructive cycles that needed to end, and the process of self-discovery. The title plays on Flatt & Scruggs’ classic bluegrass tune, signaling the album’s roots in the traditional folk that shaped the duo, while incorporating influences from their local punk and DIY scene to give it a modern edge.
