It’s a short run for Sombras Tango Cabaret, only through this weekend, but it promises to be exotic and colorful with the sensuality of The Tango, and a backstage story, too, all sung and danced to the echoing sound of the bandoneon (and piano, flute, violin and bassoon), This original dance story show was created last year for Tango 21 Dance Theater. Joyful, funny and full of surprises, the story is told through Argentine-style tango, contemporary dance, acting and original music and songs. Sombras Tango Cabaret was written by Liz Sung, with choreography by Jorge Niedas and a score by Bob Solone. Sonio Oyola is the featured vocalist and Rion Klawinski anchors it all on bandoneon. At the comfortable Edge Theater, 5451 N. Broadway. Tickets: http://tango21dancetheater.com
