Summary: Kim Gordon and Bill Nace are doing the last of their scheduled press interviews for the day. Gordon is calling in from Los Angeles; Nace from Philadelphia. They’re supposed to be talking up their experimental band, Body/Head, their new album, “The Switch,” and the fact they’ll be coming to San Francisco to play at the Lab on Saturday, July 14. But they get a little sidetracked remembering how they met for the first time 15 years ago.
