Get there early for Electric Mountain Rotten Apple Gang's opening set if you like mandolins and make sure to catch Warren Jackson Hearne. Hearne's folky, traditional arrangements--featuring Justin Collins on banjo and Paul Slavens on accordion--belong in a dark, rogue-filled European tavern in some parallel history.
Tendril (4 p.m.), Blood on the Moors (5 p.m.) and Saboteur (6 p.m.) will provide an excuse to leave. But make sure you're back in time for the Paper South from Austin, which claims members of American Analog Set and Winslow. Their atmospheric rock with ringing, echoing guitars gradually builds and settles in waves as the drums pick up from soft snare rolls to loud full-kit bashing. Unlike many bands that do this, the Paper South structure what sounds deceptively like the natural progression of an unfocused jam into tight pop-song frameworks.
