Underworld would return to the idea of internet-only releases in 2018, with the experimental year-long music-and-video project Drift. After the completion of Drift series 1, Karl explained "The Drift series has taken inspiration from [Riverrun] in that [the songs] been carried to a much higher level of completion." The song "S T A R" from Drift re-uses the percussion loops from "Lenne Penne".
