San Francisco held a huge three day concert event in Golden Gate park called Outside Lands. Over 60 artists performed with headliners including Radiohead, Tom Petty and Jack Johnson. I was lucky enough to be there and although I froze the whole weekend (I'm not used to SF weather), it rocked! My favorite part was watching Tom Petty & the Heartbreakers. His songs take me back to all sorts of times in my life. And he still knows how to put on a show!
A new element to this concert was Crowdfire.net. Its a new site that wants to give you somewhere fun and cool to upload your concert pix and vids.
