Neko Richelle Case is an American singer-songwriter and member of the Canadian indie rock group the New Pornographers. Case has a powerful, untrained contralto voice, which has been described by contemporaries and critics as a "flamethrower", "a powerhouse [which] seems like it might level buildings," "a 120-mph fastball," and a "vocal tornado". Critics also note her idiosyncratic, "cryptic," "imagistic" lyrics, and credit her as a significant figure in the early 21st-century American revival of the tenor guitar. Case's body of work has spanned and drawn on a range of traditions including country, folk, art rock, indie rock, and pop and is frequently described as defying or avoiding easy generic classification.

The tenor guitar or four-string guitar is a slightly smaller, four-string relative of the steel-string acoustic guitar or electric guitar. The instrument was initially developed in its acoustic form by Gibson and C.F. Martin so that players of the four-string tenor banjo could double on guitar.
