“Pair A Dice,” the third single from Discovery Zone’s Quantum Web, turns the dial on JJ Weihl’s diverse program of production styles toward beatific electro-pop. Kinetic drum machines and a driving bass line latch on to a head-bobbing backdrop in a lattice of melodies intertwined with synthetic flutes and a shimmer of guitar. “How can you leave / when you’re living in someone else’s dream?” JJ asks us, her voice floating up into cascading melodic curlicues. Nestled in the pop affection, equal parts dancefloor and daydream, we wonder the very same.
