As previously reported, they’ve now gone ahead and turned living musicians into holograms. Last night, Janelle Monáe and M.I.A. performed concerts on opposite sides of the country as part of a big elaborate launch event for Audi’s new A3. During the encore, a hologram projection of M.I.A. accompanied Monáe in Los Angeles, and hologram Monáe joined the real M.I.A. in NYC. Below, watch footage of them performing “Bad Girls” together (via Stereogum).
