GRAMMY®-nominated chart-topping artist Marshmello teams up with acclaimed British singer-songwriter Mae Muller on the captivating new single “American Psycho” (feat. Trippie Redd), which was released today by Astralwerks. With characteristic honesty, Muller admits to her own flaws as she addresses an ex, concluding “You put the T in toxic.” Trippie Redd tells the other side of the story on his verse. The song opens as an introspective piano ballad and Marshmello’s production builds from there, swelling to an infectious chorus.
