The Red Hot Chili Peppers perform at the 4th Annual Sean Penn & Friends HELP HAITI HOME Gala which benefited the J/P Haitian Relief Organization yesterday (January 10th 2015).
Apparently they were the surprise performance of the evening which I guess is why so little was known about this in advance (other than Chad posting a photo of his drum kit shortly beforehand). Source
