A singer-songwriter and poet, Mary Gu brings compelling lyricism to pop—with a twist. She has revisited a ’00s smash by Russian pop-rock star MakSim, but she’s at her most captivating in heart-stirring love songs inspired by her diaries. Love takes many guises as she uses tender vox as well as rhythmic raps over melancholy keys, hazy electronics, uptempo beats and evocative guitar sounds.
