When you walk alone, you are never lost. At least, that is the working principle of Homeshake, Peter Sagar’s recording project. Over his first three albums, Sagar followed his own idiosyncratic take on it, a journey that took him from hard-hitting, guitar-driven indie pop to, on 2017’s Fresh Air, a blurry take on lo-fi R&B. Now, with Helium, Sagar is taking root in aesthetic territory of his own. The landscape he once viewed from a distance now forms the foundation of his sound, and from here, he looks back at the world as though through a light mist, writing songs that feel grounded and intimate, even as they explore a scattered sense of isolation.
