After a few years of quiet, Adele's schedule is getting increasingly packed. If you're keeping an Adele calendar, here's another event to add: a live concert at Radio City Music Hall in New York City on Nov. 17. the singer will perform one night only for a television concert special, Adele Live In New York City, which will air on NBC Dec. 14. Three days after the concert, the singer will release 25, her third album; she'll follow it up almost immediately with an appearance as musical guest on Saturday Night Live, as well as an appearance on NBC's Today on Nov. 25.
