Pearl Jam postponed a show in Vienna on Wednesday after vocalist Eddie Vedder’s vocal chords were affected by heat, dust, and smoke from fires at an outdoor venue near Paris.

“To all those who were anticipating a great Pearl Jam show tonight in Vienna, we were too. However, due to the extreme circumstances at the last outdoor site outside of Paris (heat, dust, and smoke from the fires) our singer Ed Vedder’s throat was left damaged,” In a message shared on Instagram on Wednesday, the organization stated.

They said, “He has seen doctors and had treatment but as of yet, his vocal cords have not recovered. This is brutal news and horrible timing… for everyone involved,”

Over the weekend, Pearl Jam performed at the Lollapalooza Paris music festival amid a heat wave in southern Europe with temperatures far above 40 degrees Celsius (104 degrees Fahrenheit).

Firefighters in southwestern France have been battling large forest fires since July 12, while Britain recorded its hottest temperature ever on Tuesday.

“Those who work so hard to put on the shows as well as those who give their precious time and energies to attend…, as a band, we are deeply sorry and have tried to find options to still play,” They said..

“And Ed wants to play. There’s just no throat available at this time… So very, very deeply sorry.”

Tickets would be reimbursed, according to the band.

The event in Vienna on Wednesday was part of Pearl Jam’s European tour, which continues on Friday in Prague.
