A double bill — singer-songwriter Antje Duvekot and guitar-and-vocal duo Goodnight Moonshine — makes for a single evening of contemporary folk bliss at Next Stage Arts in Putney. Rising star Duvekot was born in Germany and raised in the U.S., a unique bicultural upbringing that colors her songwriting with award-winning poetic originality. A couple both on and off the stage, Molly Venter and Eben Pariser of Goodnight Moonshine are also praised for their profound lyricism. When the duo performs, evocative vocals and virtuosic guitar playing coalesce into a kind of hypnotic trance sure to captivate listeners.
