Live Nation production managers Marc Elfenbaum and Chris Dickey recall five outdoor concerts altered by the elements:

Christina Aguilera , Aug. 6, 2000, Verizon Wireless Music Center. Supporting act Destiny’s Child performed, but Aguilera didn’t make it to the stage. The weather postponement was chalked up to lightning, plus rain that flowed into the pavilion — leaving an ankle-deep pool for fans seated closest to the stage. A larger drain now accommodates water in the pavilion, Elfenbaum says.

Tom Petty , July 21, 2005, Verizon Wireless Music Center. When a storm caused a 20-second power outage in the middle of a song, neither the musicians nor the audience missed a beat. Petty returned to Verizon a year later, and Elfenbaum said crew members remarked, “This is the place the power went out and the crowd kept singing.”

Trey Anastasio , Aug. 9, 2005, Lawn at White River State Park. To the audience, this production had no snags aside from opening act Matisyahu appearing five minutes later than scheduled. But a surprise afternoon downpour waterlogged electrical gear and left a gallon of rain in a kick drum, Dickey says. Crew members scrambled to purchase 15 hair dryers to tackle soaked microphone jacks and cable connections.

Aerosmith , Oct. 13, 2006, Verizon Wireless Music Center. Cold conditions are a concern after Labor Day. The Aerosmith tour brought space heaters, and Elfenbaum says the venue purchased heavy-duty convection heaters to push the onstage temperature higher than 40 degrees. “As the sun went down, the winds died down,” he says. “It warmed up the entire area.” Nevertheless, vocalist Steven Tyler walked onstage wearing a ski cap and trench coat.

Phish , July 19, 2009, Verizon Wireless Music Center. The jam band’s reunion tour included one memorable night in Indiana. Because of lightning strikes readily apparent to the sold-out crowd, Phish extended its customary mid-show intermission from 30 minutes to 80. Keyboard player Page McConnell advised fans on the lawn to head for the parking lots and wait out the storm in cars. Many did, and the music eventually resumed. “It’s amazing how calm and orderly 10,000 people can be,” Dickey says.
