Foo Fighters frontman and former Nirvana drummer Dave Grohl, whose new HBO show “Sonic Highways” tracks American musical heritage, was in town filming in March. While in Austin he dipped into Stiles Switch for some barbecue. The restaurant passed along their brush with fame. That’s Grohl with Stiles Switch pit master, Andy Stapp, and cutter, Will Horner. Grohl tapes an episode of “Austin City Limits” Friday night, the same night the Austin episode of “Sonic Highways” airs. Check out a clip below. Wonder who Grohl might sit in with at Fun Fun Fun Fest over the weekend … King Diamond? Modest Mouse?
