Studio Tenn goes relatively contemporary with this mounting of songwriter Roger Miller’s warm and folky 1985 adaptation of Twain’s Adventures of Huckleberry Finn. The company has made an impressive name for itself with classy productions of classic plays and musicals, and this effort shouldn’t disappoint. The fact that the dearly departed Miller was such an integral part of Music City’s inroads into the pop-music record industry in the 1960s and ’70s should only deepen local interest. Artistic director Matt Logan has enlisted musician-composer-producer Don Chaffer of the Nashville-based husband-wife duo Waterdeep to supervise the score’s mix of country, bluegrass and gospel styles. Logan, always seeking out innovative modes of presentation, presents the play from the perspective of a Depression-era jug band, evoking the look and feel of the Coen Brothers film O Brother, Where Art Thou? The cast doubles as the band, and 13-year-old singer-songwriter Jackson Nance makes his theatrical debut as Huck. Other performers are John-Mark McGaha, Jack Alcott and Mary Marguerite Hall.
