Combine band members from Literature, Pet Milk, and Little Big League, and you get the chemically balanced musical element known as Mercury Girls. The assorted dream-pop group recently released its single "Ariana," which includes catchy hooks, smooth vocals, and harmonies that blend together in a near-perfect manner. Rhythmic cravings for more music from this band will soon be filled. The group is due to begin work on a full-length album with producer extraordinaire Jeff Zeigler (Kurt Vile, The War on Drugs, Nothing, just to name a few). If you're too anxious to wait for the completion of the album, then you can catch Mercury Girls opening for King Gizzard & The Lizard at Underground Arts tonight. Underground Arts, 1200 Callowhill St., 9pm, $14, 21+ - Gina Rullo
