The inaugural Outside Lands Music & Arts Festival has confirmed its final round of artist additions. Cake, Los Amigos Invisibles, the Benevento/Russo Duo, Thriving Ivory and Sila & the Afrofunk Experience will now join the likes of Radiohead, Jack Johnson, Tom Petty & Heartbreakers, Wilco, Beck, Widespread Panic, Mike Gordon and Kings of Leon in San Franciscos Golden Gate Park from August 22-24. Relix and Jambands.com will also be onsite throughout the weekend, so be sure to stop by the Relix booth to spin the prize wheel or—-better yet—-get your face on the cover of Relix in our new photo booth. Relix and Jambands.com will also help produce Outside Lands festival almanac, which will be available at the festivals entrances.
