What's more, many great musicians might not be around anymore, or just can't make it to your corner of the world. Don't fear, holograms are here. Ever since a hologram of 2Pac took the stage at Coachella, virtual performances started cropping up. But it's not just for musicians who passed away. Other acts have used holograms for an added effect, testing the limits of the concert experience. Click through this gallery to see which musicians have performed as holograms.
