Dave Grohl is one of the biggest rock stars on the planet, but he’s also something of a music historian. Sonic Highways is the Foo Fighters’ eighth album and also the name of a documentary series where Grohl explores eight different American music scenes, including Austin. This week on the Austin Music Experience, we chat with Grohl about Sonic Highways, Roky Erickson, and his lifelong love of Austin City Limits. Plus, we’ve got exclusive live recordings from Fun Fun Fun Fest 2014, captured backstage at the fest and in our Studio 1A. Hear from Courtney Barnett, J Mascis, Angel Olsen, and more. Listen below!
