Don’t worry: They did not die. We are apparently doing holograms of living musicians now, and so M.I.A. and Janelle Monae performed live, on separate coasts, with the computer rendering of the other woman. Video of Janelle’s hologram and M.I.A.’s real body is below; watch it while you contemplate the future, in which a Drake hologram lives in your apartment and makes you scrambled eggs every morning. (That is what holograms do. Ask a scientist.)
