Flea, the singer's fellow Red Hot Chili Peppers cofounder, made the announcement from the stage. 

 

“Antnony is on his way to the hospital right now and we're unable to play for you this evening," the bassist can be heard saying in fan-filmed videos making the rounds on social media. "We are devastated about it. We’re really sad, we love you so much. We live to rock. We live to fucking dig deep into the depths of our heart and rock. But unfortunately, there’s a medical thing that happened and he needed to deal with it."

 

Kiedis was said to be suffering from extreme stomach pain just a couple of hours before they were set to go on, according to reports. He arrived at a local hopsital by ambulance. 

 

At the radio station's annual event, held at Irvine Meadows Ampitheatre, WEEZER performed an extended set in the Chili Peppers absence. Other performers throughout the day included Panic! At The Disco, Garbage and Empire Of The Sun. The current lineup of BLINK-182, featuring singer/guitarist Matt Skiba, performed a surprise set.
