If you caught Luther Dickinson playing solo guitar during last fall’s Americana Music festivities, you know the Mississippi musician is a master — and that’s not even taking into consideration his fine ensemble work with electric blues band The North Mississippi Allstars. Now in his late 30s, Dickinson is one of a handful of in-the-tradition blues players who are busy modernizing a moribund 20th century art form. Dickinson is an enterprising man these days, teaming up with fellow blues explorers Alvin Youngblood Hart, Jimbo Mathus and Justin Showah in The South Memphis String Band — their new full-length, Old Times There ..., revels in the possibilities of the Bluff City jug-band aesthetic. He has also released Hambone’s Meditations, a collection of acoustic instrumentals. Tonight’s show puts the spotlight on another Dickinson side project, The Wandering, a terrific band comprising the fretboard whiz along with Amy LaVere, Shannon McNally, Valerie June and cane-fife player Shardé Thomas.
