"My mood is a pendulum/ I don't think you could handle it," sings Nandi Rose Plunkett, the synth songwriter known as Half Waif, early on "Severed Logic," her new EP's opening number. After, a second-hand-like ticking gives way to a swell of choppy, hollow-sounding beats. It's a gorgeous moment, the first of many on the six-song form/a, which drops this week on Cascine and is debuting below in full.

Plunkett, who also plays with the hyper-literary alt-country band Pinegrove, has a gifted ear for loops that sound huge but still feel like they were cut by hand, and each of these tracks unfurls like a slow-motion power ballad. The textures are immersive, and the lyrics are self-reflective. "And you have been patient through every storm/ Forgive me my baby but what's one more?" she sings on "Cerulean," her doubled-up vocals glowing like a lit match in a dark room.

"I set out to record form/a on my own, wanting this EP to be a record of what my moods sound like, if I could pull them out of my insides and amplify them," Plunkett told The FADER in an email. "This collection of songs is a look into how those moods affect my relationships, how they take me on journeys through my past, how they transport me into meditations on life and death."
