So this is pretty cool, the music festival "Doctor Music Festival" is returning to Catalonia, Spain this summer for the first time in almost twenty years. The festival lineup is pretty interesting itself... including sets form The Strokes, Smashing Pumpkins, Greta Van Fleet, The Prodigy, King Crimson and... a hologram of Frank Zappa (!) Yes. You read that correctly...a LIVE HOLOGRAM of Frank Zappa! Ha. Check out the full lineup below!
