The Double + Elisa Ambrogio + Bill Nace + DJ Ryan Sawyer

Not the aughts-era indie-pop band, but a collaboration between indie-rock eccentrics Emmett Kelly (you might know him as a frequent Will Oldham collaborator) and Jim White (Dirty Three drummer), the Double tops a free Summer Thunder bill. Also appearing are avant-rock all-stars Elisa Ambrogio and Bill Nace—of Magik Markers and Body/Head, respectively—as well as experimental drummer extraordinaire Ryan Sawyer, handling deck duties.
