Attention New York City residents who own cars or like to take taxis: July 25 is, as of now, officially a Gridlock Alert day, because early that morning Miley Ray Cyrus will take the stage at Rockefeller Center as part of Today‘s summer concert series. Also on the docket: Ashlee Simpson (July 4, unless her album gets pushed back again); Alanis Morrissette (May 23); Kenny Chesney (June 13); and a “surprise reunion concert” on May 16 that I’m stumped over, because honestly, what bands can possibly “surprise” America’s morning-TV-viewing masses by reuniting at this point? Click the picture of Miley for the full schedule. [TVNewser / Photo: AP]
