[[Michael Franti and Spearhead]] played at the Bash in [[Yerba Buena Gardens]] on June 9. Attendees received a black track jacket similar to that of the prior year, but with a smaller "WWDC" across the front and the number "11" stitched on the back. This was the final Apple event hosted by Jobs during his lifetime, before his death four months later.
