Swedish House Mafia's Ultra 2013 set (and last concert ever too)
My favorite set from Ultra Music Fest was from Swedish House Mafia. It was so good, I felt like I was high, and I didn't have any drugs that day nor did I buy/drink anything the hours before I heard them. By the time their set started I was sobering up from the alcohol I had drank earlier in the day. Overall though, Ultra was an amazing experience that I hope to re-live next year :)
