The electropop band Paramore dismayed fans with tickets to the Saturday, July 22, concert at Chase Center by announcing that the performance would be rescheduled for Aug. 7 just hours before the scheduled show.

“Due to sickness within the touring party, we will be rescheduling our show tonight at Chase Center in San Francisco to Monday, August 7, 2023,” astatementfrom the band’s official Twitter account said.

The concert at the home of the Golden State Warriors was scheduled to begin at 7 p.m. The announcement of the postponement came at 5:15 p.m. The band said tickets to Saturday’s concert would be valid in August.

“If you cannot attend the rescheduled date and would like a refund, instructions will be sent to all ticket purchases and refunds will be offered for the next 7 days. We look forward to seeing you all soon at the next Paramore show,” the statement said.

Concertgoers expressed disappointment on social media when they heard the announcement. “Find it odd there’s no apology or basically any F’s given to the fans in that statement,”one tweet said. Anotherperson said, “Hope everyone gets well soon. But this is real tough for the people who camped out for days, especially with the show in just a couple hours.”

But some people expressed a sense of humor. “I will be submitting my bridge toll receipt for refund as well,”a person tweeted.

The outfit fronted by Hayley Williams is on tour behind its latest album, “This Is Why,” its first new release since 2017.

“It summarizes the plethora of ridiculous emotions, the rollercoaster of being alive in 2022, having survived even just the last 3 or 4 years,” Williams said of the album in a statement. “You’d think after a global pandemic of f—ing biblical proportions and the impending doom of a dying planet, that humans would have found it deep within themselves to be kinder or more empathetic or something.”
