Though each had been produced by the late Jim Dickinson, Memphis' Amy LaVere and Oxford's Shannon McNally never played together until Dickinson's son Luther called both of them (along with Valerie June and Sharde Thomas) to the studio for sessions that produced the roots-music revue the Wandering. Versatile, roots-oriented singer-songwriters with a similar look and sound, LaVere and McNally struck up a chemistry, in the studio and onstage, and soon spun off of the Wandering into their own duo. The pair released Chasing the Ghosts — Rehearsal Sessions, a quickie seven-song, 30-minute EP recorded and put out by Archer Records in October, in conjunction with a Southwestern tour. Among the seven songs are stripped-down reworkings of two highlights from LaVere's most recent album, "Stranger Me" and "Great Divide," which now, like most of Chasing the Ghosts, features the companionable vocal interplay of LaVere and McNally. The pair make their official Memphis debut at the Hi-Tone Café on Saturday, December 29th. Doors open at 8 p.m. Admission is $10.
