Socks, Fanta, and Cheap Bodywash
Freak-Out Odds: Very High
An artist knows that they've "made it" once promoters start bending over backwards to track down five-foot inflatable animals, "three fresh limes (and a knife to cut them)," enough Redbull to trigger cardiac arrest, and a "bag of cheese strings" because contractual obligations dictates as much.
From "one pair of white socks and one pair of black socks for size nine" to "good quality men's shower gel" and "four cans or bottles of a carbonated orange drink, preferably 'Fanta,'" Deadmau5's exhaustive concert rider is extraordinarily thorough.
Any discrepancies on the festival's part, "no matter how seemingly small minor or insignificant," should be addressed immediately in an effort to avoid an artist meltdown.
Of course, that's if Zimmerman's actually on the bill.
