We went to the Oracle Appreciation Event (held in association with JavaOne and Oracle OpenWorld). It was held 2015-10-28 at Treasure Island, an articial Island outside San Francisco.
The musical headliner was Elton John. He had a long high-energy show, almost two hours.
The second act was Beck, who didn't get start until about 11:40. We watched a few numbers, and then got in line for the Ferris Wheel.
