ALT CTRL is home to the latest and greatest in alternative music. Here, it’s as much an attitude as a sound—music that keeps things a little left of center and rough around the edges. This week, Hayley Williams returns with “Glum,” one of the 17 surprise tracks she just self-released. The Paramore vocalist and singer-songwriter is known for her kinetic performances and sunny, sky-high vocal range, yet “Glum” strikes a more somber chord. An acoustic guitar and a steady beat take the slow and steady route through a dreary forecast as Williams ruminates on loneliness and melancholy before belting out the chorus (“Do you ever feel so alone/That you could implode and no one would know?”). Williams may be “Glum” on this track, but we’re certainly not as she turns the page on a new chapter.
