The retro-futuristic duo (Mica Tenenbaum and Matthew Lewin) hails from LA by way of the uncanny Valley, churning out trippy DIY videos made from random VHS footage and mailing weird brochures to fans like a secretive cult. But on debut full-length Mercurial World, their polished synth-pop demands to be taken seriously, though their playful spirit abides—emulating the effects of a VOCALOID with their mouths, kicking off the album with a track called “The End”. Tenenbaum and Lewin blend the nostalgic with the contemporary, combining Y2K-era bubblegum, the disco grooves of mid-aughts indie-dance crossovers and the space-age sheen of hyperpop for a 45-minute sugar rush; don’t miss “Chaeri”, 2021’s best pop song about being a bad friend.
