What is Epsilon Naught? It’s Brainiac’s big move — an electric field he created to permeate a vacuum. All 27 songs are labeled cryptically in maths, with each equation playing its part in articulating an ancient existential problem. These beats — sampled in part from beloved funk and soul oldies — flow naturally and can fit in the background of any setting or situation. Brainiac’s awe-inspiring vocal loops wax poetic on love, space, death, and dreams, scored by bright, bumping arrangements.
