The thread lines of any given Black Mirror episode speak to the here and now in beautifully tragic and brutal brush strokes. “Nosedive” examines our obsessions with being liked on social media; while the award-winning “San Junipero” scrapes up the layers of an afterlife fated to the cloud. Through each griping tale, the human existence, as rich and intoxicating it can be, is filtered through a sour, stunningly-harrowing lens. Los Angeles singer-songwriter Brad Byrd feels such a sharp blade of technology with his new single, “1982,” premiering today.
