Singer Lauryn Hill cancelled a planned performance at Ram’s Head Live in Baltimore on May 12, the latest in a string of late-appearances and no-shows.

Since gaining notoriety as a member of The Fugees in the mid-90’s, Hill has become better known for her eccentricity, lateness and canceling performances at the last minute than her music.

After being late for a performance this past weekend in Atlanta, Hill canceled the Baltimore performance citing “unforeseeable circumstances.” The two cancellations were the latest in a long string of missed performances, including dates in London, Texas, Israel, and others.

Hill also failed to appear as planned during the 2016 Grammy Awards on Feb 15. The president of the National Academy of Recording Arts and Sciences, Neil Portnow, told USA Today that Hill’s performance was meant to be a surprise. “She was there for , completed it and left the building. Then she did not get back in time to make the show,” Portnow told the newspaper.

Representatives for Hill disagreed with the account.

“The Grammys announced a performance by Ms. Lauryn Hill prematurely and without approval,” her representatives wrote in a statement. “Ms. Hill had concerts all weekend, leaving no time to prepare, and was uncertain she would even be able to make it to L.A. in time to rehearse for the event. Any performance that could have happened was never confirmed, and should not have been advertised as such. Ms. Hill was invited to do a collaboration with an artist she appreciates. The performance was intended to be a surprise and unfortunately due to its last minute nature, was unable to come to fruition.”

Hill showed up two hours and 20 minutes late to her May 6 concert at Chastain Park Amphitheater in Atlanta. According to The Atlanta Journal-Constitution, she performed for approximately 40 minutes before the amphitheater had to cut her off due to the venue’s strict 11 p.m. curfew. According to Atlanta ABC affiliate WSB-TV, fans will be able to get refunds for their tickets.

In a May 8 post on her Facebook account, Hill attempted to explain her late appearance.

I don’t show up late to shows because I don’t care. And I have nothing but Love and respect for my fans,” she wrote. “The challenge is aligning my energy with the time, taking something that isn’t easily classified or contained, and trying to make it available for others. I don’t have an on/off switch. I am at my best when I am open, rested, sensitive and liberated to express myself as truthfully as possible. For every performance that I’ve arrived to late, there have been countless others where I’ve performed in excess of two hours, beyond what I am contracted to do, pouring everything out on the stage.

As of press time, Hill had not offered an explanation for the cancellation of her Baltimore show.
