DeMarco has become only more popular in the past decade. “Chamber of Reflection,” a teetering, synth-driven track from “Salad Days,” is ubiquitous on TikTok, and has been streamed nearly a billion times. DeMarco himself has more than twenty million monthly listeners on Spotify, a remarkable number for a dude who plays dazed, quivery guitar songs about whatever’s on his mind. A TikTok account dedicated to his work has more than eight hundred thousand followers and features videos of DeMarco telling jokes that are sometimes scatological and always absurd. (Picture, say, a pleasingly unhinged-looking DeMarco, hoodie up, placing a fake phone call in which he attempts to order half a million dollars’ worth of poop and pee.) DeMarco’s fans have always been young, but he thinks that they might be getting younger. “There was a point where I kind of understood my audience. Now I have no fucking idea,” he said. “I grew up and they didn’t.”journey-inline-newsletterinline-newsletter
