NEW YORK — Lady Gaga celebrated her 28th birthday with an energetic but short concert at the Roseland Ballroom in her first of seven concerts at the closing venue.

Gaga performed for an hour Friday night in front of a feverish crowd. She was in top form as she sang nearly a dozen of her songs, including “Just Dance,” “Born This Way,” “Poker Face” and “Applause.” The concert’s main surprise: It didn’t last long. After she ended, fans waited for the pop star to hit the stage again.

The New York-born singer’s actor-boyfriend Taylor Kinney attended the concert.
