Tap dancers have performed to classical music before, and they’ll do it again. But you can be sure that no one will do it like Savion Glover. Two years ago he unleashed “Classical Savion” on the world, performing to music by Vivaldi, Bach, Bartok, Mendelssohn, and Astor Piazzolla. Chicago never got to see that program, but this weekend Glover’s performing one day only with the Chicago Symphony Orchestra to selections from Duke Ellington’s orchestral suite The River (which Alvin Ailey used for a dance of the same title in 1970). Ellington wrote that the “Giggling Rapids” section is like a child “that races and runs and dances and skips and trips all over the backyard”–possibly an odd fit with Glover’s sometimes heavy-footed approach. But LA Times critic Lewis Segal praised that section in July, writing that it and one other not hampered by sound problems were “brilliant, the footwork sometimes decorating the musical line, sometimes providing a kind of engine under it, but also fusing with it here and there, as if Glover and Ellington were on exactly the same wavelength.” Other musical selections (sans hoofing) include the overture to The Magic Flute and Mussorgsky’s Pictures at an Exhibition; Edwin Outwater conducts. a Sun 9/9, 4 PM, Pritzker Pavilion, Millennium Park, Michigan and Randolph, 312-742-1168.
