Grammy Award-winning singer-songwriters Shawn Colvin and Steve Earle are touring together this September on a jaunt they’ve dubbed “Songs and Stories, Together Onstage.” The show comes through town tonight and it promises to be a good one, even though each artist is probably best known for albums that came out over a decade ago. Since Earle can be a bit prickly, Colvin should help smooth out his rough edges with her stories and songs. They’ll swap songs, sing a few duets and share some stories. If previous shows are any indication, expect the whole thing to conclude with Earle’s raucous anthem “Copperhead Road.” (Niesel)
