Australian pop mastermind Sia, American dance-music alchemist Diplo, and British hip-hop innovator Labrinth have made some of the most memorable singles of the ‘10s, and their collective releases underneath the LSD banner continue that run. “Genius” combines an insistent whistled hook, a skip-step rhythm, and startling touches like a beamed-in choir into a singular statement that shoves pop into the 2020s; “Audio” mirrors its lyrical salute to “the bomb bomb beat” with snare-trimmed island rhythms and Diplo's enthusiastic toasts. The trio come from different places musically and geographically, which energizes their giddy, surprising bangers.
