Kings of Leon played recently at the Oracle Open World music extravaganza in San Francisco a few weeks back, opening for Pearl Jam. While I'm not a huge KoL fan, I thought it would be interesting. It was certainly loud. In fact, it was too loud for my Sony RX100 camera, resulting in a lot of distortion. Heck, I could feel my internal organs vibrating from the bass drum. And it was kind of cool when Eddie Vedder came out to join them.
Despite the poor audio quality, I've posted a few songs on YouTube shot directly from one of the big screens for those who want to check it out. And I'll follow up with the Pearl Jam post shortly.
