Erika Wennerstrom's 2018 solo album, Sweet Unknown, is a tour de force. You may know and love her music from her work with the Heartless Bastards. This solo album allows her to dive deeper into herself, while maintaining the vocals NPR describes as "warm yet gritty, throaty yet sweet, gigantic, yet intimate."
