Vancouver quartet Weed’s new single, “Stay in the Summer,” off their forthcoming Running Back LP, out April 7 on LEFSE Records, is a blaring, funereal dissection of the sadder side of nostalgia. Deliberately, but prettily disdainful in melody and forlorn in voice, the guitar chugs along in heavy resonance, slamming on whammy bars and dipping the tones to irk notions of longing for the past, while distant, watery vocals smooth everything over in a numbing coldness. “Lose yourself in time,” the song begs, shedding light on a personal inner struggle. “Can’t take you back.” Running Back is Weed’s second full-length, following 2013’s Deserve, expressing a fuller self-knowledge both musically and meditatively.
