LPX is the punchier solo vehicle of Lizzy Plapinger, lead singer of dark electropop duo MS MR. She debuted with the self-produced single "Tightrope" in January 2017, which followed her second album with Max Hershenow by 18 months. The song's big hooks, distortion, and impassioned vocal delivery teased a gutsy full-length out later in the year. ~ Marcy Donelson.
