Lauryn Hill performs during the 2016 New Orleans Jazz & Heritage Festival at Fair Grounds Race Course on April 29, 2016 in New Orleans, Louisiana.

Lauryn Hill says she will "make it up" to fans angry that she arrived over two hours late to an Atlanta concert Friday night (May 6) and performed for fewer than 40 minutes.

Hill wrote on her Facebook page Sunday (May 8) that she doesn't show up to shows late because she doesn't care, but because of the artistic process. The challenge, she said, is aligning her energy with the time.

The concert was held at Atlanta's Chastain Park Amphitheatre, which has an 11 p.m. noise curfew. Many in attendance expressed their outrage about the situation on social media.

In the note, Hill said that she will announce details of how she will make it up as she has them.
