Aerosmith had to cancel their Wednesday night performance in Concord, CA due to heart-related complications suffered by drummer Joey Kramer.
Tickets for the show, which was part of the band’s Let Rock Rule tour, are being refunded at point of purchase.
A statement on the band’s website reads, “The band regrets not being able to perform for their fans.”
Kramer, 64, will undergo heart surgery, TMZ reported, although it could not be confirmed.
The next scheduled date on the tour is Saturday, August 16th at the Gorge Amphitheatre in Quincy, WA.
