Marty Stuart and His Fabulous Superlatives are what’s absolutely right about today’s country music. Superb instrumentalists and songwriters, as well as dynamic performers, the talented quartet is steeped in country’s venerable history while bringing the sounds of Hank and Lefty, Lester Flatt and Johnny Cash into the 21st Century. The band’s latest, two-disc album, “Saturday Night and Sunday Morning” (releasing Sept. 30), surveys country’s twin dimensions of the sacred and secular, meeting as they do at the midnight hour. Expect an uplifting romp through both, when Marty Stuart and His (aptly named) Fabulous Superlatives perform at Durham’s Carolina Theatre Friday night. More info at carolinatheatre.org.
