Two Australian sisters have crafted a steadfast sort of sunny pop as L.U.V. Though neither have reached the age of 21, Maya and Vivi Mohan sure know how to write a catchy pop tune. “You’ll Never Let Me Go” splices together simple layers and a graceful melody with sparkling polish. As our American summer begins to wind down, that shimmering guitar riff feels just right. The bright guitars slowly blend together as the verses and refrain become a call and response, turning relentless love pursuit into echoes of sunshine.
