Gabrielle Louise and David Rynhart, a Denver-based duo featuring original songs in the Americana/folk/roots idioms, will present a show at Hard Rock Cafe in Empire on Jan. 16. The multi-instrumentalists and songwriters toggle between genres and instruments to craft an eclectic show, rich with vocal harmonies ranging from smoky jazz to old-time folk. The storytellers perform their songs on two guitars, a mandolin, a traditional Irish flute, a peppy ukulele and one sultry piano.
