Silly lovebird Americana tonight at Davey’s

Americana music often comes loaded with a certain kitschy absurdity. Onstage, husband-and-wife folk duo Stacey Earle and Mark Stuart tell stories, make jokes and inflict puns. (Earle’s debut solo album carries the atrociously cornball title Simple Gearle.) And the band’s touring 1999 Chevy Suburban is billed as “the crew” on the pair’s website, its odometer displayed in pasted numbers on the back of the vehicle (454,788 miles, according to the latest post).
