Annahstasia Enuke couldn’t become the star her early handlers wanted her to be. When Annahstasia sings, she makes use of her full range, but her low end is where the magic happens. That singular instrument guides her debut album, Tether, a self-possessed set that straddles folk, rock, and chamber pop. Drums appear sparingly; Liao’s basslines and Annahstasia’s cadences more often than not set the pace, which tends to be slow. “I’m porcelain/Sitting on your highest shelf/I’m gonna fall/I’m gonna fall without your help/Take care of me/Before anyone else,” Annahstasia pleads on “Take Care of Me,” teetering in her upper register.
