Yes its true. Janet Jackson and Metallica are going to be performing in San Francisco tonight. And it is all for a good cause.
UCSF Benioff Children's Hospitals announced this morning that Janet had been added to the performance lineup for this evenings benefit concert. It's all presented by Salesforce.org in conjunction with Salesforce's annual Dreamforce conference.
Now tickets are pretty pricey! They start at $1,000. And are available here.
