7:30 p.m., Prost. Free.

This gig was originally scheduled for Studio Joe, but something got in the way. Now, it’s free at a bar that’s just carving out its place among local venues (Prost is attached to Willy D’s in the River Market, but with its own entrance around the corner). Look for it to be fuller than usual on a Thursday night. Acoustic folk’s first couple is passing through on their farewell tour. For the last 17 years, Earle and Stuart have made literate, harmony-rich music together, together releasing a handful of albums and touring ferociously (they come on the “Drive Her Till She Drops” tour, an effort to drive a 2000 Chevy Suburban with more than 400,000 miles on it into the ground). But after this tour wraps up sometime next year, the married couple has said they’ll each return to the solo work they’ve pursued intermittently over the years (both, early in their careers, spent time in Stacey’s brother Steve Earle’s backing band, the Dukes). In other words, this is your last chance to catch them together in Little Rock.
