VIVIANA GUZMAN and her marvelous quartet, “Performers of the World”, offer a downright tantilizing audio/visual excursion into this wonderful world of Tango 101. The selection of pieces in this live performance recorded on August 17th, 2001 at the Old First Church in San Francisco is a compelling study of the art form that reaches into historic roots to give the listener a greater appreciation of the many styles and evolved development the tango has traveled.
