A high-school physics teacher by day, and an independent troubadour at night with two albums out, Erika Lee Sherger resides in that confessional singer-songwriter zone where she lays naked her emotions to write about her own shortcomings, riding her blind horse, withstanding a friend’s suicide and losing her mom. Genre-wise, this Morris County (Boonton Township) resident is solid Americana. Call it alt-country or indie-folk if you want. ‘Bad Wolf’ is the follow-up to her 2021 ‘Like Birds’ debut.
