Why do these feativals like Coachella, Bonaroo, Lopapalooza, SXSW, Essence, Glastonbury and SupaFesf continue to book these retired artists who aren't relevant to the younger crowd will attends these events. I'm pretty sure the predominately 18-24 crowd at Coachella was not here for Outkast performing songs for 10-15 yrs ago. Why didn't they get Kendrick Lamar, J. Cole, A$ap Rocky, Rick Ross, Nicki Minaj, Schoolboy Q or Drake
